The deaths of three Michigan rappers whose bodies were found in an abandoned apartment building in early February were related to gang violence, state police said, asking members of the public who might have information about the case to come forward.

In a series of tweets Friday, Michigan State Police confirmed they were continuing to investigate the triple homicide of Armani Kelly, 28; Dante Wicker, 31; and Montoya Givens, 31, who were reported missing after their January 21 performance at a Detroit club was canceled.
