Investigators have not commented on a potential motive. Neighbors describe Person as a friendly fixture at the corner store.

“He was a nice guy,” said Paul Merrill.

Said Jacquelin Bencosme, “He’s been great to me and great to my kids and very helpful to us and I can’t believe they did this to him. I feel like crying right now.”
