Published at 4:50 a.m.: Police have charged a 14-year-old boy as an adult with first-degree murder in the death of his 7-month-old sister.

Johnathan Aguiluc, 14, of White Oak, Md., is being held without bond in the death of Larissa Yanes.

Investigators in Montgomery County say that the girl's mother, 39-year-old Gloria Yanes, left her apartment in the 11600 block of Lockwood Drive at 10:30 p.m. Thursday to go to work, leaving Aguiluc to watch Larissa.

During the evening, detectives say that Aguiluc beat Larissa, which caused her to cry. The teen then said he covered Larissa's nose and mouth with his hands until she stopped crying and placed the baby in her car seat.

Gloria Yanes returned to the apartment at around 5:30 a.m. Friday. Around half an hour later, she attempted to wake Larissa up to feed her.

When Larissa did not respond, her mother called the police and fire/rescue. Larissa Yanes was taken to Holy Cross Hospital, where she was pronounced dead of her injuries shortly before 7 a.m.

Aguiluc is scheduled to appear in court for a bond review on Monday.

By law, a 14 yr old is allowed to babysit a child.
Therefore your suggestion of a neglect charge doesn't apply.

Babysitting is one thing. This boy was left alone with this child all night long while the mother worked. And he beat her, let's dont forget that little bit of information...so obviously he was not a fit "babysitter". He didn't just beat her out of the blue. Something had been going on with him before this incident and the mother had not dealt with it.

That's pure conjecture on your part. Kids do do things out the blue and sometimes even for no apparent rational reason.

    He figured it would be a good "lesson" for his sister.

      Give him the needle now. No point in the taxpayers wasting money on this trash.

        I'm a little confused on this story...It says the baby was "beat"...but then it says mom tried to wake the baby to "feed" her....wouldnt she had seen the injuries before trying to wake her to "feed" her....sounds a little iffy to me...

          If the baby died before the bruises could form, or the child was dressed--I am sure the baby didn't "look" beaten or dead, just sleeping. Maybe the child was on a routine when Mom got home from work, and it was wake up and feeding time.

            What are the charges for the mother? She is guilty of child negligence at the very least. Yes, it's sad she just lost a child, but that doesn't negate her culpability in the matter.

              You can turn off the comments all you want, but it won't change the facts. First of all, a 14 year old boy should nevr have been left responsible for a 7 month old baby all night long. Second, he obviously had some issues that should have been addressed if he had it in him to beat a baby. Third, I think that the mother needs to take some responsibility for having left the child. I know how hard single parenthood can be, because I have lived it. But sometimes we have to make the hard choices. Had this mother made the hard choice, her baby might still be alive.

              Maybe his issues just came down to resentment. He had his mom to himself for thirteen years, he might have been jealous of the time and attention the baby took. I don't know, but you would think the mother might have taken note of that. There is just so much that can go wrong leaving a baby with a 14year old for extended periods. Besides this, obviously.

                Some 14 year olds can babysit a baby, some cannot. That said, it sounds like there is something else going on with this kid; mental illness, hostility toward the baby, inability to empathize, something. I shudder to think what he will be like when he gets out of prison.

                Even though I despise what this turd did, I'm not sure he should be tried as an adult. He's still 14 almost an adult. Maybe put him in jail for like 8 years or something I don't know there is an easy answer. He is a murderer. But so young to toss away his life.

                  Keep him in heavy counseling until 21...he can be rehabilitated.

                    The kid was a bit young to be watching a 7 month old baby. My son is 14 and he watcheds his sister all the time but she is 6 years old. Obviously some mental issues with the boy. God Bless the Baby and the Boy.

                    I think there is a big difference between babysitting and leaving a possibly mentally ill and certainly sleep-deprived teenage boy alone throughout night after night with an infant. She was probably running out the door every night and praying that nothing would happen and was probably feeling lucky that her son hadn't done anything bad yet. Well, now it has. How many nights of being up and warming up bottles and rocking her back to sleep was this kid stuck with until he lost it? This mother was courting tragedy for a while and now this child is dead.

                    AJ-1018729: I think you have a the best point here. This was night, and possibly the act of a very sleepy, tired 14 year old whose baser instincts got better of him. This kid is little more than a child himself. I don't think he was in his senses when he did this. I have seen grown men lose patience around a cranky child at night. He needs to be severely punished, yes, but trying him as an adult is senseless.

                    I do think it should be illegal for anyone under 18 to watch children at night. They should be in bed, sleeping, not watching over other children.

                    This mother had no clue that her 14 year old was capable of violence? Surly at some point he showed evidence that he was not able to deal with stress.

                          The mother and the 14 year old are both equally culpable.

                          They both caused this to happen. It is terrible but they both need to be put away.

                            Sad all around. It sounds like she's a single mom.

                            Teenagers have no frontal cortex - but I guess he'll have to pay for this with many years in the slammer to get better decision-making skills.

                              This crime is horrible and tragic. However, I also blame the mother for leaving her 7 month old baby overnight with her 14 year old! Even prepared mature parents have difficulty caring for a baby. It is irresponsible of the mother to expect her young teenaged son to care for a baby overnight. It's exhausting work, and who knows if he had been caring for this baby every night, and then attending school during the day. As horrible as the crime was, it was unfair to put this 14 year old into this position to begin with.

                                I am sure that there are many immigrant families who do this where the parents take jobs like night shift office cleaning because of language, education and lets be real, citizenship status issues. I wouldn't hesitate too much in leaving a capable, experienced teenager girl in charge occasionally, and I stress occasionally very strongly, but boys are different, they need more food, more sleep. They have less patience. To leave them to be up all night tending to a newborn is just not a good idea.

                                  That mother is as guilty as anybody!!!!! There must have been at least a few "red flags" over this teen!! I find it hard to believe, she didn't realize he had some sort of problem!! Parents REALLY need to make sure of the personality type they are leaving their child with when leaving them under another individual's care. After all, if you have to go out to work or any place, the bottom line is, it is your responsibility as a parent to protect your children, esp. babies!!!

                                    What a terrible thing. The poor baby was just doing what babies do and her brother kills her. I feel like the others above though.....this 14 year old was not capable of caring for an infant or maybe there is some mental issues as well. I hate it when we don't get the entire story about these cases. It's more about rushing to get the news out on this and beating the others with the story.

                                    My prayers go out to this tiny angel!!!

                                      What he did was wrong, plain and simple. I'm not excusing what he did and he deserves to be punished for what he did, but who knows if this kid had some psychological issues or if he knew what he was doing? If he was known to have issues then the mother shouldn't have left the child with him without her supervision. It's wrong to blame the mother when it's not like she went out with a group of friends and decided to throw the kid at him. Nobody knows the background of this story for sure until more details come out. Regardless of whether the kid feels remorseful for what he did, the fact is that this family lost one of their own and my condolences goes out to the mother and other loved ones.

                                        We need to make it criminal for teens to breed more teens. I bet the mother was under 20 and unmarried when she had the boy. And how did she support him and where was the father of either of these kids?

                                          And I bet she was around 25, just subtracting 14 from 39.
