ANDOVER, Minn. - Two juveniles face second-degree murder charges in connection with the hit-and-run death of a 17-year-old in Andover. A third person is expected to be charged Tuesday afternoon.

A 17-year-old from St. Francis and a 16-year-old from Andover have been charged in Anoka County Juvenile Court related to the Nov. 10 incident. Both were taken into custody over the weekend. The third person, a 19-year-old man suspected of driving the car, was arrested Monday.

According to the charges, both teens were inside a vehicle that hit and killed Tristan Robinson of Nowthen. Charges state all three people met up with Robinson and a friend, who they found using Snapchat, to buy marijuana. The three parked down the street and made one of them go to the house to make the deal. He didn't have any money, to which they suggested he just take the weed.

The teen went to the house. Robinson and his friend came out, walked to the car with the teen and showed everyone the marijuana. The buyers explained they didn't have enough money, to which Robinson's friend said he'd remove some to sell it at a cheaper price. The driver of the car then pulled into the driveway of the home, according to the complaint.

Robinson, his friend, and one of the suspects entered the home. According to the charges, when Robinson removed some of the weed, the suspect took the bag and ran out the front door, with Robinson in pursuit.

One of the people in the vehicle pulled out a gun, warning Robinson to let them go. Robinson grabbed one of the door handles, lost his footing and was dragged by the car as the driver backed out of the driveway. The complaint states Robinson fell and as the driver turned to drive down the street, at least one person in the vehicle heard "a couple of thumps."

"The hopeful gain from that robbery would have been a small amount of marijuana," said Cdr. Paul Sommer of the Anoka County Sheriff's Office said following the incident. "There's no words to describe the tragedy that we see here today."

Robinson was a student at Andover High School. Kari Lund, Robinson's aunt, said her nephew was an aspiring rapper who planned on pursuing his dreams in California. His aunt said Robinson's nickname was "Bubba" and he loved hanging out with friends riding four-wheelers, fishing, skateboarding and fashion.
