Police in Wisconsin are on the hunt for a 15-year-old boy who allegedly gunned down his girlfriend and seriously wounded her mother Thursday.

A manhunt was on the way Thursday evening for Martice Fuller, who is considered armed and dangerous, the Kenosha Police Department said.

The high school student allegedly shot dead 16-year-old Kaylie Juga, with whom he’d been having a relationship, at a home in Kenosha.

A 39-year-old woman, identified as the girl’s mother, was also shot and taken to a local hospital in serious but stable condition.
