After 20-hour SWAT standoff, man suspected in cop's death found dead

(CNN) -- A late-night 911 call. Police race to the house of a venture capitalist in an upscale suburb of Detroit. Shots are fired at officers and one of them is killed. The house is surrounded, a SWAT unit is summoned and after a 20-hour standoff punctuated by more shots, the homeowner and suspected shooter is found dead. Two lives are over. One, that of a 12-year veteran of the police force, a married man with four children. The other, seen through legal documents and online resumes, appears to have spiraled downward from a high-flying career as a top-level auto executive with a wife and child to that of a divorcee facing legal issues and financial woes. At 10 p.m. ET Sunday, police officers responded to a report of gunfire at the home in West Bloomfield Township, Michigan, according to a police spokesman. Officer Patrick O'Rourke was shot several times by the gunman and later died at a hospital, said Lt. Tim Diamond. After a 20-hour standoff during which police knocked out a wall in the home and the suspect fired more shots, police sent in a robot outfitted with a camera, according to a release from the West Bloomfield police department. When a team of police officers entered the room they discovered Ricky Coley was dead, a police dispatcher said. The cause of death had yet to be determined, the release said. It appeared that the 50-year-old was on the verge of losing almost everything.
