On the evening of August 3, 2015, 26-year-old Parnell Robinson was visiting his girlfriend and her young daughter at a public housing complex on Ames Avenue in Saint Paul. Robinson was on the front porch talking with a friend when he playfully teased the friend about having to walk to the store. A neighbor, 24-year-old Lepierre Cortia Carpenter, overheard the remark and interpreted it as a personal taunt amid ongoing tensions between the men that had been playing out on social media.

Carpenter retrieved a handgun, and despite his sister’s attempt to intervene, went outside and shot Robinson from behind. Robinson was heard asking why before collapsing; the Ramsey County Medical Examiner determined he died from multiple traumatic injuries due to the gunshot wounds. Carpenter tossed the gun into the yard, returned briefly to his apartment, then surrendered to arriving officers, saying it was him and expressing regret.

Carpenter was arrested and charged with second-degree murder; his bail was set at one million dollars. If anyone knew Parnell, his whereabouts that night, or the tensions between him and Carpenter, please share what can help the case.
