In the early hours of December 30, 2018, deputies with the York-Poquoson Sheriff’s Office were called to the Penniman neighborhood of Williamsburg, initially for a report of shots fired. Then, they were called again: A 20-year-old had been fatally shot in his home. They spend the next several days talking to Mason’s friends, searching for surveillance footage, and collecting evidence. Since then, investigators have canvassed the neighborhood, turning over every possible clue that might help piece together what happened on December 29, 2018. They believe they might be close to answers — as long as they’re able to track down the man who might know what happened.
