Demetrius Cook, 33, was found dead in his University City, Missouri, home in the 1300 block of Sheridan Drive on the afternoon of January 19, 2017, after officers responded to a welfare check. Officers entered the unlocked residence and located Cook suffering from multiple gunshot wounds; he was pronounced dead at the scene and a homicide investigation was opened.

Investigators early on said they believed Cook had been specifically targeted rather than the victim of a random act. Despite the unlocked door and lack of obvious forced entry, police have been unable to identify a suspect; no arrests have been announced and the case remains open and unsolved. Cook, known as Manny to friends and family, was buried following a funeral at Wade Twin Chapel later that month.

Anyone with information about Cook or the circumstances of the shooting is asked to contact the University City Police Department.
