James Ngoc Nguyen, 53, was found shot in his car on January 31, 2016, off Magnolia near Michigan Avenue and Inkster Road in Inkster, Michigan. An engineer and father of four, he was remembered by family and colleagues as kind, self-sacrificing and friendly.

Investigators looked into possible motives that emerged early in the inquiry. The family said Nguyen bought and sold used cell phones online, and police examined whether a Craigslist transaction may have played a role. A second man was found fatally shot in his car in the same area about a week later, prompting concern that the shootings could be connected.

Witnesses described a suspect fleeing the scene as a lighter-skinned Black male, about 30 years old and 5 feet, 7 inches, wearing a dark gray hooded zippered jacket and Timberland boots.

If anyone knew Nguyen, his routine buying and selling locations, or saw someone matching the description in that area, please share what was seen.
