Detroit police are looking for a man they believe committed a triple shooting that left a 64-year-old woman dead and two others seriously injured about 3 a.m. Monday.

Detroit police identified the suspect as 32-year-old Cornelius Dennis, described as a 5-foot-9 black man weighing nearly 160 pounds. He was last seen driving a black 2016 Chevrolet Silverado 4x4 pickup with an extended cab, a Tonneau bed cover and Michigan license plate no. "DSL1817."

Police say the suspect entered a home in the 5200 block of Kensington, walked upstairs and fatally shot the 64-year-old woman. He then proceeded to shoot a 29-year-old woman and 33-year-old man who were also on the home and are expected to survive.

The Detroit News reports that the 29-year-old woman previously dated Dennis; the 33-year-old man is her new boyfriend and the 64-year-old woman was her mother.

Detroit Police Chief James Craig said there is a history of domestic violence involving the suspect and his former girlfriend.

Detroit police say Dennis may be armed and dangerous.
