Man charged in fatal St. Paul shooting

The incident occured on March 15 in the 600 block of Elfelt Street in St. Paul. After Thomas wrapped his hands around his girlfriend's neck, Franklin, who was the girlfriend's cousin, proceeded to try and protect his cousin from the attack. Thomas left shortly after.

Around 15 to 20 minutes later, a 17-year-old who was in the home reported hearing a loud knock at the door. The woman allegedly let Thomas back in and the 17-year-old reported hearing a commotion. Though the girlfriend attempted to stop him, the teen reported seeing Thomas pull the trigger and shoot Franklin in his left eye.
