The chase is on
"Tony, give us priority," Bessner is heard saying into a police radio. "Chasing an ATV east on Rossini from Reno. It's a red quad. Black male, black shirt."
A security camera mounted on the Embassy Coney Island restaurant at the corner of Gratiot and Rossini was pointed at the parking lot, but in the background, it showed a view of Rossini where Grimes' ATV appears followed closely by a State Police patrol car. Just as the ATV exits the camera frame, it bounces back into the frame after striking a parked Ford F-150 pickup. The security camera footage didn't include sound, but police cameras did.
“He flipped,” Detroit Police Officer J. Williams said before quickly reporting the accident over his radio.
Williams and his partner, Officer Cameron Boersma, pulled up about 20 seconds after the crash. As they stepped out of their police cruiser, Bessner was bent over Grimes, who lay in the middle of the street beside the pickup, his overturned ATV nearby.
A view from another security camera shows the overhead emergency lights on Bessner’s squad car appear to have been activated 24 seconds after the crash. State Police policy requires troopers to turn on their emergency lights, sirens and in-car video recording systems during a pursuit.
State Police and prosecutors wouldn't say whether the lights were on during the chase. About the time the lights appear on video, Bessner’s partner, Trooper Ethan Berger, can be seen walking away from the car.
State Police spokesman First Lt. Mike Shaw said there is dashcam video from that patrol car, but he wouldn't describe what it shows citing the pending criminal case.
Shaw said the cameras typically are activated in one of several ways. They begin recording automatically when a trooper turns on the emergency lights. Troopers also can activate them by pushing a button on the dash or by turning on a microphone worn on the trooper's belt.
“Have EMS step it up,” a person at the scene urged soon after the first two Detroit police officers arrived. As police waited for the ambulance, Grimes’ condition quickly worsened.
“I don’t know if he’s got a pulse anymore,” a voice is heard over the radio.
As another Detroit patrol car arrived, officers radioed for another update on the ambulance, noting Grimes' pulse was weakening.
