Soccer Coach Questioned After Death Of San Fernando Valley 13-Year-Old: Report

LOS ANGELES, CA — The soccer coach of a 13-year-old boy found dead in Ventura County days after he was reported missing was questioned by police about the San Fernando Valley teen's disappearance, according to a report citing law enforcement sources and court records.

Mario Edgardo Garcia Aquino, 43, was arrested by LAPD detectives Wednesday morning on a warrant for an unrelated sexual assault charge, NBC Los Angeles reported.

The family of Oscar Omar Hernandez, whose body was found this week near McGrath State Beach and the Santa Clara River, identified Garcia Aquino as the last person to see the teen before he disappeared, the report said.

"This individual has not been arrested or charged in connection with the Hernandez case," LAPD Public Information Director Jennifer Forkish told NBC Los Angeles. "Our investigation is ongoing."

Hernandez was reported missing by his family on Sunday after he failed to return home, according to police.

The investigation led detectives to an "area of interest" in the City of Oxnard, where a coordinated foot search of the area took place. During the search, a body matching the description of the missing teen was discovered on Wednesday.

The medical examiner in Ventura County has since confirmed the body was Hernandez.

Hernandez's family is now demanding justice.

The boy, a student at Sun Valley Magnet school, had taken a train to Lancaster to visit an acquaintance, and his loved ones began to worry when they couldn't get in touch with him.

When they tried to call Oscar, the acquaintance would answer and say that the teen couldn’t come to the phone, the family told NBC Los Angeles. That's when they became suspicious and filed a missing persons report.

“My brother was one of those people that would greet anyone. He had no evil in his heart,” Hernandez's sister told KTLA in Spanish. “If he encountered anyone, he would have a conversation with them and be friends with that person.”
