Luis Walker-Carrion, 28, was shot and killed in East Chicago, Indiana, in the early morning hours of August 24, 2014. He was at his home in the 3700 block of Deodar Street with his girlfriend when another man called the woman. A heated phone argument followed and, according to reports, Walker-Carrion went outside carrying a shotgun to confront the caller. The encounter in the alley near the home turned violent and Walker-Carrion was fatally shot. He was taken to St. Catherine’s Hospital and pronounced dead at 5:11 a.m.; the Lake County Coroner classified the death as a homicide.

The alleged shooter, a 34-year-old man from Whiting, Indiana, fled but was stopped shortly afterward in a traffic stop and arrested without incident. The police chief said the case might involve a question of self-defense that would be presented to the prosecutor. Walker-Carrion was described by those who knew him as a proud Marine, a loving father, and an outgoing, funny friend who enjoyed dancing and singing.

If anyone witnessed the confrontation in the alley or has information about the events leading up to the shooting, please come forward.
