SUPERIOR TWP. (WWJ) - One year later, the slaying of a Washtenaw County woman remains a mystery. Now her family is reaching out to the public for help to discover who killed her, and why.

Kelly Campbell-Brown, 53, was found dead in her home in the 1900 block of Evergreen Lane in Superior Township, near Ypsilanti, on Oct. 6, 2018.

She'd had family until around 8:30 p.m. the night before, according to investigators, and when they weren't able to get in touch with her the next day, they got worried.

Family members who went to Campbell-Brown's home to check on her found her dead on her bed.

An autopsy concluded that she'd been shot, but there have been no arrests, and there are no known suspects in the case.

Growing up, Campbell-Brown attended Huron High School in Ann Arbor where she was a member of the Sister’s Club. After high school she worked at the Comfort Inn before moving on to St. Joe’s hospital where she was employed for 16 years. According to Crime Stoppers, she was "faithful as a domestic cleaner" with a few clients who referred to passionately as the “Queen of Clean."

She loved entertaining her family in her home, as she'd done the final night of her life.

As the investigation continues, Crime Stoppers is offering a cash reward of up to $2,500 for information that leads to the arrest of Campbell-Brown's killer.
