SAN ANTONIO – Arthur Hernandez Martinez, Jr., 21, was formally indicted by a Bexar County grand jury this week on a felony manslaughter charge in the shooting death of a man at a West Side home in November. Martinez allegedly shot John Paul Alvarez, 20, around 3 a.m. at a house in the 8000 block of Westshire Drive, according to San Antonio police. Martinez first told police the victim shot himself while playing with a gun, and then said a gunman shot the man and fled, according to San Antonio police. Martinez told police he “never meant to hurt John." “I cried because he was my brother," he said, clarifying that they were friends and not related.
