8:17 PM: Just got a call from neighbors of the family looking for Byron, missing about half an hour near 56th and Dakota. He’s in his 70s and has dementia; he’s white, with white hair, 5’9″, thin, wearing a red/white/blue collared shirt and tan pants. Police are searching too. If you see him, call 911.
8:20 PM: Good news! He’s been found, safe.
