Police in Michigan are searching for a 22-year-old woman they say is “armed and dangerous” after fatally shooting her boyfriend and brother Sunday morning in Independence Township.

Police say Ruby Taverner is 5 feet 2 inches tall and weighs around 115 pounds, with a thin build. She currently has purple hair, according to WXYZ.

She may be carrying any or all of three weapons registered in her name — two 9mm handguns and a .38 caliber handgun, the Oakland County Sheriff’s Office said.

According to MLive.com, deputies responded to a 911 call from a neighbor in Independence Square who reported gunshots at about 3:20 a.m. The found the body of 25-year-old Bishop Taverner, the suspect’s brother, in the living room, and 26-year-old Ray Muscat in a back bedroom. Muscat and Ruby Taverner lived in the apartment together, although police said they didn’t know how long the couple had been together.
