A woman who was reported missing by her family was found dead inside a home in Detroit.

Police say 40-year-old Alonda Cathey was found in the home on Cooper Street near Gratiot and I-94. Police have one person in custody in connection to Cathey's murder -- and her brother tells us the suspect is a relative.

FOX 2 is told Cathey was shot to death in what appears to be a robbery. Cathey's minivan was spotted outside the Liquor Party Place on Gratiot.

Her body was found Tuesday night with a gunshot wound. Her brother, Alonzo Cathey, helped lead police to the suspect.

"I bumped into the family member at the liquor store; he was driving her car," Alonzo says. "I asked her where my sister was at because she would never (leave). He said he found her car on the side street. And it just didn't add up; it didn't make sense so I called the police and kept him there.

"We went back to her house and discovered her dead and he was the last one with her."

Investigators towing her vehicle were searching for clues after they say her credit card had been used this morning. Police haven't given details about the suspect in custody.

Cathey had been missing for at least 24 hours before her body was found.
