This is so awful

[French Castanut]

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.
