A 31-year-old man accidentally shot his friend, who later died, and then fatally shot himself Saturday night in northwest Indiana.

Officers responded about 9:30 p.m. to a person shot at a get-together in the 7100 block of Osborne Avenue, according to Hammond police. As the first officer arrived at the scene, he heard one additional shot.

Witnesses said 31-year-old Bryan Carr accidentally shot 31-year-old Jonathan Culp, police said.

Carr and witnesses at the scene tried to administer first-aid to Culp, but then said he could not live with what he had done and shot himself, police said.

Culp, of Highland, Indiana, was taken to Franciscan Health Center in Hammond, where he died at 10:10 p.m., authorities said.

Carr, of Hobart, Indiana, was pronounced dead at the scene, police said.
