It sure does not sound like he was 20 miles from his home.
The police reports posted online originally had his mother’s home address. That’s been removed or blacked out. I got over ten miles in distance to the address in the Sattila Shores subdivision.
So 2 miles in, a mile loop, and 2 miles back.
Looks like a 5 mile run.
About 40 minutes exercise at the average 8mph.
About 30 minute run at 10 mph
