"I hit her really, really hard."

That's what a Chandler dad told police about his 7-month-old daughter, who died at an area hospital this morning after suffering a skull fracture likely caused by her father, 21-year-old Sergio Thomas.

According to court documents obtained by New Times, about 8 a.m. yesterday, Chandler police responded to a call that a 7-month-old girl was unresponsive in her home at 1231 West Whitten Street in Chandler.

The girl was taken to Phoenix Children's Hospital, where it was determined she had a bi-lateral skull fracture, subdural brain bleeding, and bi-lateral retinal hemorrhages.


Police interviewed both Thomas and the girl's mother and discovered the two were separated but had joint custody of the girl, which they shared on various days of the week.

At the time she sustained the injuries, the girl was in the lone care of Thomas.

Police asked him what happened and he claimed he had no idea -- he said he woke to the sound of his sister screaming because the baby was found unresponsive in her crib. 

When pressed by police, Thomas copped to what really happened.

Thomas told police he was frustrated because the girl had woken him up in the middle of the night. He told police he put her in her crib about 9 p.m. Sunday night. By 11 p.m., the baby woke up and started crying.

He told police, the baby's crying fueled his anger issues, so he went into her room, yanked her out of the crib by her arm, and brought him into his room, where she fell asleep in his arms.

About 3 a.m., the baby woke up again -- and again, Thomas was furious.

He told police he pulled his arm out from under the baby, which caused her to fly off the bed and hit her head on a wall.

Again, yanking her by the arm, Thomas moved the girl from his bed to her crib, where he gave her a bottle and changed her diaper. But the baby wouldn't stop crying and Thomas shook her violently to get her to stop.

Then he threw her with "force" into the crib. As the baby continued to cry, Thomas says, he "hit her really, really hard" -- with about 80 percent of his strength, he says -- in the back of the head.

He hit her on the back of the head two or three more times before slapping her in the face several times, and went back to bed -- the baby still crying in her crib.

She died about 7 a.m. today.

Thomas is currently on release for an August domestic violence arrest, in which the girl and her mother were both injured.

He's been booked on two counts of child abuse, and one count of first-degree murder.

You are all under 25 yrs of age. This I can tell by reading what you have written. One there is no DA in Arizona. DA stands for District Attorney. In Az we have City, County and AG, Attorney General. DA is for Federal Cases. You idiots watch to much TV. Two A grown ass man killed a helpless 7 month old baby girl. His or not his baby. A full grown man killed a small helpless baby. Three The Mother, the Father ....Just because you can does not mean you should. Never, never get the baby's involved in your triangle messy whorish lives.  Stop and grow a brain.

A second chance? For a grown man that beats to death a 7 month old baby? Grow a brain.

I know Sergio is very remorseful. He does have anger issues like so many people do and he didn't have the skills he needed. Sure you never hit or shake a baby. He did and it caused her to die. He should do some jail time to learn that you have to deal with your issues before your issues deal with you. This is not a crime that deserves the death penalty. He was not out seeking to kill someone like the Baseline killer. He is a young man who now knows a whole lot more than he did before. He should get 15-20 and an education and some counseling and then have a second chance if he shows that he is willing to deal with his anger and control issues. Everyone should get a second chance.

Does everyone know that Kristen cheated on sergio with a guy named vinny and that the child that Sergio killed was actuallyVinnys and that she was pregnant again with a third fathers kids and she just had a miscarriage from the stress ofRylee being killed... Yeah what a great mother out screwing other guys and not taking care of her kids already with Sergio those are the facts and I know them so maybe kristens family should get their facts straight before trying to defend her all the time damn welfare babies!!!!!!

The mother is a very good friend of mine and all you worhtless pieces of shit getting on here saying she needs to be punished ad itsh er fault really need to shut the hell up and grow up and of u saying u knew the mother personally if u really did u wouldnt be saying such bullshit about her because anyone that knows her knows she is a wonderful mom and does everything for her kids. I would of never guessed in a million years that sergio would ever do this and neither did she! Its sergios damn fault not the mothers. all of you really need to geta reality check and grow up if this was you you would feel diff aboutit! just like Rye's family said dont put your two cents in unless you know the damn facts because i guarantee you more than 3/4 of you know not a damn thing!

Its interesting to see how people claim to know sergio, kristen, and their daughter Rylee. As family, I know what some are you saying and I understand. But, Kristen was and still is an excellent mother. Always patient with her children. ALWAYS. The incident in August was not as big of deal as you all claim to be. Sergio came into their room, Kristen laying in bed with rye in her arms feeding her, sergio grabbed hold of the mattress and flipped it up on them. The cops were than called, and he was arrested. The very next morning after being arrested the charges against him and rye were dropped by the DA. He had two pending misdemeanors. He spent four nights in jail, and than was released. He and the mother were told sergio was able to have contact with the children as well as kristen again. He was never convicted. Kristen moved out the night he was arrested to her moms, and sergio had moved in with his father. They remained separated, Kristen and Sergio and a custody agreement. For the person who said the family court would have told kristen sergio should have contact with the children you are correct. Kristen started off with the children going over to sergios (lived with his father and sister) only during the weekend. Than after awhile sergio requested more time with the children so she allowed and they had joint custody agreements. She never once would have ever imagined that he could have ever hurt their children, EVER. He was always very patient with them and loved to show them off. Both of the children were always extremely happy. Came home with smiles on their faces everyday. Never was afraid of anyone, and was always higher up in development than most. Kristen loves/loved her kids with all of her heart. Always taking pictures of them, taking them out, art project. Her kids where her life. She had to hold her baby girl in her arms as she passed away, knowing rye's father did this to her. She is heart broken and misses her baby girl endlessly. Sergio Thomas is the only one to blame in this instance, and maybe the state if they where so "concerned" about the charges in August. Even thought all charges where dropped and they were told it was ok for sergio to be apart of the childrens lives. I miss Rylee extremely. I know nothing can mend the hurt i feel for Kristen's family, She always did the best she could for her children. I believe as well as Chandler P.D among many others that Kristen took all steps necessary for her children. She is a victim as well as that baby girl.

I have stress in my life. I am a single mother with no family, and no friends that are willing to help me. I have to deal with a lot of shit and I don't ever think about taking it out on my baby. Was it the baby's fault that he had stress in his life, that he had a breakup or whatever? People break up everyday and they don't commit murder. He has commited murder. His kids should have been what kept him going and give him hope or strength not make him angry. If he had killed someone else's baby you all would not be defending him. What is worse than killing a random baby? KILLING YOUR OWN baby!! It wasn't an accident or a mistake. Punching a baby over and over on her head and slapping her in her face was not going to stop her from crying!! Why didn't he call someone to help him or just walk away and ignore her? Anything would have been better than what he did. And as for the mother, no matter what kind of mother you are, no mother deserves to lose a child this way. She didn't make him do this and she had no control over what he does. He was the children's father and she probably thought she was doing the right thing by allowing her kids to see their father which is something a lot of mothers have problems with being mature enough to do this. Judges pass orders all the time in domestic violence cases that in spite of the problems between the mother and father the judge says the children still need to see their father. She made a mistake in letting him have the kids alone but if she thought he would kill her baby she would not have let them go there. And making a mistake does not make her a bad person or a murderer, Sergio Thomas is the murderer, let's not forget that. Sergio Thomas is an evil disgusting person that IS NOT sorry for what he did and proved himself that it was no accident by doing what he did to the baby AND THEN GOING TO BED!! What kind of person can sleep at night after murdering a baby? Maybe if he called somebody or called 911 she wouldn't have died. That's ok though, he is going to get beat and raped everyday in prison until it kills him.

This happens to children everyday; if you are not outraged, you're not paying attention.Arizona's social workers/CPS get paid the least out of any state in the US. If they could get more money, more children will be saved. If they could get enough people to care, children will be saved. Sergio has no remorse for what he did and Kristen could have prevented her daughter's death; if only they weren't selfish parents/people.I am very sorry for everyone's loss. Baby Rylee is better off in heaven with the angels than being here in this hell on earth.

this is horrible! all you shouldn't be talking the way you are about someone..you obviously don't Sergio or the mother. so keep your mouths shut. the baby was an infant an insist infant infact! so shut the hell up.. there is no reason anyone should ever hit an baby in that way a father especially shouldn't that was his first babygirl he shoulda been watching her rather then getting mad at her infact that he knows exactly how babies are since he has an older son as well. the mother shouldn't have allowed him to be left with her in anyway especially since he was just "released" on domestic violence charges four months prier. & now look she is dead & I say it coulda been prevented.

This child wasn't even his child. I know himPersonally an his wife cheated on him and had someone else kid she is now pregnant with her third child and it's also the third father her tubes need to be tied because she can't even take care of these kids I'm sure this is what fueled Sergios rage. Don't get me wrong he should not have done what he did but the mother is to blame as well!!!!

What is with this recent string of fatal blows to children? Nobody told these people that it's not good to hit an infant?

While living outside of Arizona, I saw a few statewide campaigns aimed at reinforcing "Never, Never Shake a Baby" in response to a few isolated shaken baby incidents. It looks like Arizona needs to adopt that but change it to "Never, Never Hit a Baby."

Or perhaps "Never, Never Hit a Baby... By the Way, Shaking a Baby Is Also Ill-Advised, So Don't Do That Either" would be more appropriate to cover all bases.

We can put a stop to this! I wish someone would put together a BIG UPRISING for or children. When, WHEN, is it ever gonna stop! Make the penalty so hard that ppl will think twice if they knew the consequences were much much worse. Now, he he get heat, roof over his head, 3 meals a day, more rights than normal, no rent, no taxes, wow what a life! It just don't make sense! Maybe jail is the place u outta be!

I know the mother personally.... He needs to die and the mother needs to be punished as well, for letting that monster anywhere NEAR her children while knowing how abusive he his. He has beaten her and her children before, and this is the result.. Both of them shouldn't be aloud near children.

I believe the child died at Phoenix Children's, not Chandler. That's where the guy was arrested as well (yes, I know this is a separate case from the 4 year old last week). Just FYI. Guess the holiday season brings out the best in people.

Its not about the social workers/cps. Its about being too young to have children-its about morals and its about supplying first time parent classes-what to do when a baby cries non-stop. Most likely the mother is hurting deeply at this time. She is going to need tremendous support from her friends and family--if she would have thought for a moment that her daughter was not in safe hands--- I dont believe she would have left her alone with him.

the domestic violence indecent was DROPPED by the DA!. Saying they didnt see sergio had violent tendencies. If the mother had any idea this could be a possibility for her childrens' future you really think she would have let them with him?? NO, she wouldn't have.Now she gets to mourn and feel this hurt forever and visit her babygirl in the cemetery. NOT COOL!

Get your facts straight...the DA...yes the DA dropped those charges due to "lack of funds"...so in a custody battle she couldnt of used those dropped charges to keep him from seeing the kids...you people are ignorant judgemental fools that breed hate...and you are no better than Sergio...for it was hate and ignorance that drove this murder!!!

Yeah this could have been prevented 21 years ago.HIS mother should have washed the sperms out that would have been him.

Now the State has to give jack ass a 84th trimester abortion with a gas chamber.

This piece of scum is a LOW LIFE THUG.

This is bullshit! She seems to take care of her children very well you have no idea what your talking about! Everyone on here needs to stop talking shit about the mother and focus on this child murder! He should be beaten the way he did his daughter that poor little girl will never get to see her first christmas!

REALLY? How does anyone know that this is going to happen...do you honestly believe she had a crystal ball and could see the future? This was a very ignorant thing to say...I know that if the mother had even a small inclination that this man was going to murder her child she wouldnt have allowed the visitation...shame on you for being so judgemental during a mothers worse time of grief!

If you know the mother you would also know theres wayy more to the story

Agreed, I know them very well also and I know more to the story then I bet most of you do and I think that it is sad that this happened, the only person I feel bad for is the daughter, whowas a beautiful happy baby and the fact that he had a charge set on him 4 months for something like this, when they were lying in bed and he walked in and threw them off the bed, do not get me wrong the mother is a sweet person but she knew what he was willing and able to do. She left her daughter alone with him and look what happened. there is only one role of a parent, keeping your children safe and she messed up. I am not here to bash on the mother or anyone else but I am here posting this because most of you are posting out of anger and frustration and I wanted to solidate what happened previously to monday. I love the mother and the baby was gorgeous.

I know the mother as well and for you to say that she needs to be punished as well is outrageous!! Shut your mouth, you have no idea what your talking about. Someone should knock you out for talking such rubbish out your mouth.

Double checked with the Chandler PD. You're correct. It was the Phoenix Children's Hospital. Thanks for the heads up -- it's been fixed.

I can't wait till Kristen goesTo jail for this and now she is pregnant again what a whore she can't keep her legs closed butI guess when you live off the state it's ok. Mine as well have all the kids she can while the state pays for it. What if she had to pay for everything then where would she be???

Guest

Yeah because a violent guy is definitely a safe haven for a baby. Sure the mother is hurting but she knew how he is, i hardly think that she thought he was responsible enough for her baby.

They we we still married. Cheating is cheating yes she had Sergio baby then VInnies then the third guy. And now she's about to give birth again. Number 4. She did a lot to him and all he wanted was his family. He did everything for his family. We know the truth all of it. Their entire existance together. He loves his family and just wanted to do everything for them. Kristen knew that but didn't care. She always dropped the kids off with Sergio she didn't want to be bothered. No one knows u are all speculating going off of print and here say. We know the truth. And anyone that knows the TRUTH will understand. He must miss his children and his wife very much. I pray for all of them yes including Sergio. He is a good person that did a bad thing and I'm sure he is hurting just as much as we are. May GOD bless all of them and take good care of Ry
