West Bloomfield Police Lt. Timothy Diamond confirmed Tuesday that Ricky Coley, who is suspected of killing Police Officer Patrick O'Rourke on Sunday and engaging police in a 19-hour standoff, shot himself in the head, based on preliminary findings.

Diamond said he had not received official confirmation regarding the manner and cause of death from the Oakland County Medical Examiner as of Tuesday afternoon.

Police discovered Coley dead in his bedroom about 6 p.m. Monday.

Diamond confirmed that Coley is suspected of fatally shooting O'Rourke through a door and drywall from inside the master bedroom of the home at 4558 Forest Edge in West Bloomfield.

, located in the North Woods Forest subdivision, at 4,037 square feet with an estimated market value of $573,000.

Police arrived at the home about 10 p.m. Sunday when Coley's family members, who were helping him move from the home, reported hearing a single gunshot from the bedroom, Diamond said.

Five West Bloomfield police officers entered the home and approached the room believing it was likely Coley committed suicide, Diamond said, and then he opened fire through the closed door and a wall of the bedroom.

Diamond would not discuss where or how many times O'Rourke was struck by gunfire.

Within hours, Oakland County sheriff's deputies sent a remote controlled robot into the home to see if Coley was alive. He again opened fire on the robot.

As the day progressed, police fired on the home, sent in other robots and tore down section of the home's outer walls. They eventually confirmed Coley was no longer alive, Diamond said.

Michigan State Police Trooper Lt. Josh Collins, who heads the state police Bomb Squad and is based in Lansing, said the robot that first confirmed Coley's death had an extendable arm with a camera capable of picking up images in low-light situations, which was transmitted to officers at the scene.

"The image of the robot was he was laying on his bed," said West Bloomfield Township Supervisor Michele Economou Ureste, who remained in close contact with authorities throughout the standoff. "The image from the robot was from toe to head and he was surrounded by knives, weapons and wearing white goggles."

Police closed Pontiac Trail, which travels past Coley's street, and evacuated about 15 houses.

West Bloomfield Patch reported that Coley had recently lost the home he died in during a divorce settlement and had financial troubles related to a company he operated.

Coley's profile on the LinkedIn professional networking website lists him as a chairman emeritus with CNC Holdings LLC and a graduate from North Carolina Central University School of Law.
