As authorities continue to investigate Tuesday’s fatal shooting of a fleeing motorist by a Shelby Township police officer, two key questions remain:

Why did the man jump out of his vehicle and run after the officer pulled him over for what police will only say was a “moving violation” and did he shoot at the officer as witnesses claimed?

The Macomb County Sheriff’s Office has taken over the investigation, a common procedure in an officer-involved shooting.

Sheriff Anthony Wickersham said deputies cannot comment at this time.

“Why he ran has not been determined,” Wickersham said Wednesday.

An autopsy conducted Wednesday morning by the Oakland County Medical Examiner’s Office determined the 41-year-old Troy resident died from multiple gunshot wounds, according to Bill Mullan of the Oakland County Executive’s Office.

Authorities have not released the man’s name.

According to police and witnesses, the incident took place about 3:15 p.m. when an officer pulled over the driver of a white Dodge Caravan, who stopped in the parking lot of The Hot Spot Coffee Company on Van Dyke Avenue, south of 22 Mile Road.

The driver of the van reportedly got out of the vehicle and began to run as the officer repeatedly ordered him to stop. The chase proceeded behind the Hot Spot Coffee Company, where the officer deployed his Taser device, according to a news release issued by Shelby Township police.

The Troy man then allegedly pulled out a firearm and was ordered to drop the weapon by the officer, who then fired and struck him.

Investigators said the suspect was taken to a local hospital where he died from his injuries. His name is not being released, police said Tuesday evening.

A witness told The Macomb Daily he saw the Troy man fire two shots at the officer who then returned fire. He said he heard between four and six shots being fired.

At least 10 yellow evidence markers were seen placed on the ground by police investigating the incident behind the coffee shop.

The news release did not state if the suspect shot at the officer as the witness claimed. Sgt. Kevin Bailey of the Shelby Township Police Department on Wednesday said he could not comment on the weapon issue since the matter has been turned over to the Sheriff’s Office.

Sheriff Wickersham said he anticipates the review of the incident will take about a week or two to complete, depending on when deputies receive the medical examiner’s autopsy report.
