Police interviewed several witnesses and were able to identify the suspect vehicle involved in the shooting.

A week later, St. Paul police received a tip from the Minneapolis Police Department that officers had stopped a similar vehicle on Oct. 7.

St. Paul police reviewed body camera video from the traffic stop and saw that vehicle matched the suspect vehicle.

Police spoke with the owner of the car who said her boyfriend had taken the vehicle to the Twin Cities on Oct. 1 and returned on Oct. 8.

When officers spoke with the man, he said Carpenter had gotten into the back of his vehicle on the evening of the shooting and that they had been driving around. The man told investigators Carpenter later exited the vehicle and that he heard several gunshots. The man told investigators Carpenter then ran back and got in the car.

Another occupant of the vehicle told a similar story.

On Oct. 22, officers stopped a vehicle for an equipment malfunction and found Carpenter in the backseat of the vehicle.

In an interview with investigators, Carpenter denied any involvement in the homicide.
