An Apple Valley man set up a marijuana deal in Bloomington last week and fatally struck the seller with his SUV while driving off with the drug, a criminal complaint filed Tuesday alleges.

Lamont Eugene Williams Jr., 21, faces a second-degree unintentional murder while committing a felony charge in connection with Thursday’s hit-and-run killing of a 21-year-old man near his home in the 8300 block of 11th Avenue on Bloomington’s east side. He remains at the Hennepin County Jail ahead of a Wednesday first court appearance on the charge. An attorney for Williams was not listed in the court file.

The victim, whose name has not been released by authorities, died of blunt force trauma at Hennepin County Medical Center. His injuries included a brain bleed, skull fracture, broken collarbone, rib fractures, and cuts and bruising on the lower back and elsewhere consistent with road rash, the complaint says.

Police were called to the area on a report of the man lying in the street with broken bones and difficulty breathing. Officers found the man, identified in the complaint by his initials A.L.G., on the ground near a snowbank. He was gasping for breath.

One of A.L.G.’s family members told officers that A.L.G. said “Monty,” later identified as Williams, had contacted him and that he agreed to sell Williams some “weed,” the complaint says.

A.L.G.’s mother said she was sitting on the couch when he told her he was going outside to sell something. About two minutes later, she heard yelling. She looked outside and saw A.L.G. leaning into the passenger side of a small, dark-colored SUV. He appeared to be halfway in the vehicle.

She said she could see A.L.G. and someone inside the SUV pulling a backpack back and forth. As this was happening, the SUV accelerated and she shouted to her other children. They went outside and found A.L.G. lying in the street a few houses down from their house.

Williams was arrested early Friday near his home; he’d been driving a grey Jeep Renegade registered to his mother, the complaint says. Officers found in the SUV a 9mm handgun on the front passenger seat and a black Coach backpack with plastic bags of marijuana that totaled about 264 grams, or more than 9 ounces.

A search of Williams’ phone showed the two men exchanged messages through Facebook about A.L.G. selling him “smoke.” A.L.G. sent Williams his home address.

The complaint says Williams wrote to A.L.G. at 8:31 p.m., “Here.” Four minutes later, Williams wrote, “I’m in this Jeep.” Location data of Williams’ cellphone showed it moved east from the area of A.L.G.’s home at 8:37 p.m. Six minutes later, Williams messaged A.L.G.: “My fault gang I had to.”
