A young U.S. Marine has been declared brain dead on Sunday after getting shot in the back of the head in South Los Angeles, L.A.

According to LAPD Media Relations officials, Carlos Segovia was shot once in the head near 31st Street and Western Avenue at about 11:30 PM on Friday. Police said that a vehicle pulled up beside his, and a suspect or suspects opened fire at him.

According to authorities Segovia was not in uniform when he was shot. The family of Segovia contacted ABC7 using the hashtag #abc7eyewitness and said that the 19 years old was home on military leave.

His family said that, for several years, Segovia volunteered for a group that feeds the homeless, and six months ago, he became a U.S. Marine to serve his country.

Claudia Perez of L.A. on Cloud 9, the organization where Segovia volunteered said, "All I know is someone did this to him. They didn't think about anything - who he was, who he is. It just hurts us, you know?".

Segovia's family had been asking for two things, prayers and for anyone with information on the crime to come forward to police.

The LAPD said that the shooting was not related to any gang, and they did not have information on any suspects or their vehicle.
