LOS ANGELES (AP) — Officials say a 21-year-old Army veteran was shot to death after a dispute at a party to celebrate his return from Afghanistan.

Los Angeles police Lt. Paul Vernon told City News Service that Francisco Garcia had left his party and was on a sidewalk in the San Fernando Valley when a man pulled up and yelled at him before shooting him early Sunday.

Authorities say Garcia died at the scene.

Vernon says police believe the suspect targeted Garcia following a dispute Saturday. No arrests have been made.

Detectives say they do not believe those involved had been at the party.
