CLEVELAND -- Attorney General Mike DeWine has announced that the Bureau of Criminal Investigation is leading the investigation of last Thursday's deadly police pursuit.

BCI took lead in investigating at the request of local authorities. The team of investigators also includes detectives with the Cuyahoga County Sheriff's Office and the East Cleveland Police Department.

"The Ohio Attorney General's BCI agents are experienced in investigating officer-involved shootings," DeWine said in a press release. "I've tasked them with pursuing this case aggressively, to go wherever the facts take them, and to track down every lead. We want to ensure the community that this will be fully and fairly investigated."

Upon completion of the investigation, the Attorney General's Office will report its findings to Cuyahoga County Prosecutor Timothy McGinty.

"This incident included a lengthy police chase through many communities. We urge anyone who saw anything that might assist in this investigation to call BCI at 855-BCI-OHIO," DeWine said.

The police pursuit involved a 22-minute chase that began on St. Clair Avenue after an occupant inside a vehicle was believed to have fired a shot. In the end, police fired 137 rounds at the two suspects inside the vehicle, killing both.

On Tuesday, the Medical Examiner's Office reported that the driver, 43-year-old Timothy Russell, had been shot 23 times. The passenger, 30-year-old Malissa Williams, was shot 24 times.
