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. According to court documents, Coley was scheduled to have an early intervention conference on Monday morning in his recent divorce case, a day on which he was reportedly about to be evicted. In her filing, Coley's ex-wife, Deniece, alleged he attacked her on June 12 and she moved out of the house. Deniece Coley said her husband had cheated on her and subjected her to "physical, mental, emotional and psychological abuse." The divorce was granted six days ago, according to CNN affiliate WDIV.
