A man says he fatally shot a friend he failed to recognize after an evening of drinking in Far East Dallas, police say.

The suspect, whose name has not been released, said he accidentally killed Nuno Guillermo, 26, as he was walking up to his parents' home in the 10100 block of San Juan Avenue, near Peavy Road, according to a police report.

The suspect said he pulled a revolver from his pocket when Guillermo approached, and it went off by mistake.

Guillermo, who was shot in the head, died at a nearby hospital. The suspect is in custody and faces a charge of manslaughter.
