Four adults were found shot to death Wednesday in a Detroit house that police say was known for drug activity.

Officers were called to the home just before 9 a.m. and found the bodies of two women and two men, said Detroit police Sgt. Omar Feliciano. He said the home had been raided by police in the past, though he didn't know if any drugs were confiscated or anyone was arrested.

All four victims found there Wednesday had been shot, Feliciano said.
