A man who spent his time trying to improve his neighborhood was shot to death on Monday while streaming on Facebook Live. Prentis Robinson,55, was gunned down roughly one block from the police headquarters where he had just stopped to report a stolen cell phone. The suspect, 65-year-old Douglas Colson, surrendered Tuesday to the Union County Sheriff’s Office, a lifelong Wingate Resident, has been arrested before. In the footage, which Facebook has removed but was viewed by NBC News, Robinson can be seen walking down a street in Wingate with a cell phone attached to a selfie stick. The person, whose face isn’t visible, then appears to fire four gunshots and Robinson tumbles to the ground.
