Johnathan Aguiluz to be tried as juvenile in sister's death

ROCKVILLE, Md. (AP/ABC7) - A Montgomery County judge says a 14-year-old boy will be tried as a juvenile in the death of his infant sister last month.

Johnathan Aguiluz also faces a reduced charge of second-degree murder, instead of the first-degree murder charge that prosecutors initially brought.

Authorities said Aguiluz struck his sister, Larissa Yanes, and covered her mouth with his hands to get her to stop crying. Their mother returned home from work to find her child unresponsive.

Investigators now believe that most of the injuries on the girl's body were from insect bites. The case will be moved from adult court to juvenile court.

Aguiluz is being held at a juvenile detention facility in Montgomery County.
