WEST BLOOMFIELD TOWNSHIP, Mich. (AP) - Police in suburban Detroit say a man suspected of gunning down an officer who responded to a trouble call has been found dead.
    
West Bloomfield Township police Lt. Tim Diamond says a search team entered the suspect's home about 6 p.m. Monday and found 50-year-old Ricky Coley's body.
    
Diamond says it isn't yet known if Coley killed himself.
    
Police had been surrounding the house in the affluent community since Sunday night. That's when an officer was shot to death while responding to a report of a possible suicide attempt.
    
Police say the gunman fired through a door and wall, striking Officer Pat O'Rourke.
    
Coley was a former auto industry executive whose venture capital company faced legal scrutiny. He was also going through a divorce.
    
THIS IS A BREAKING NEWS UPDATE. Check back soon for further information. AP's earlier story is below.
    
Authorities involved in a long standoff Monday with a man suspected of killing a police officer in suburban Detroit destroyed part of his home in an effort to get him out.
    
TV stations aired aerial video of construction equipment clawing away at the second floor of Ricky Coley's home in West Bloomfield Township late Monday afternoon. At least two armored vehicles were also in the upscale neighborhood, which was evacuated after Officer Pat O'Rourke was gunned down Sunday night.
    
Messages seeking comment about the demolition were not immediately returned by township police or the Oakland County sheriff's department.
    
O'Rourke was part of a team of four or five officers who responded to a 911 call that Coley had tried to kill himself or needed medical attention around 10 p.m. Sunday, Lt. Timothy Diamond said.
    
They called Coley's name as they climbed the stairs to the second floor and "were met by shots fired through the bedroom door and the drywall," Diamond said.
    
Coley, 50, a former auto industry executive, was alone inside the house Monday afternoon. Volleys of gunfire were heard hours earlier, but it was unclear who fired them.
    
"The sheriff's department is still trying to persuade this guy into a peaceful resolution," Diamond said before the big machine was sent in.
    
Records show Coley headed a private equity firm, CNC Holdings.
    
The U.S. Labor Department recently filed a lawsuit accusing Coley of mishandling money that was supposed to cover employee insurance at a Bad Axe, Mich., trucking company, Translogic Auto Carriers, which has been controlled by CNC since 2008.
    
The lawsuit says Coley also transferred $342,000 from Translogic to himself or his affiliates. Creditors forced Translogic into bankruptcy court in 2010.
    
Diamond said relatives called 911 and fled Coley's home Sunday after hearing shots. He said the stress of Coley's recent divorce and financial problems likely were factors.
    
O'Rourke, a West Bloomfield officer for 12 years, was married and had four children. In a memo to fellow officers, Lt. Curt Lawson said a "scene can turn in unexpected ways," despite the best training and preparation.
    
Officers closed roads in the area and evacuated at least 10 families from their homes.
