If you live in Genesee County and heard a large explosion Friday night, deputies have an explanation.
It turns out people set off a Tannerite explosion in Alexander on Dodgeson Road just after 9:30 p.m. Dispatch received dozens of calls from concerned residents whose homes were rattled as far away as LeRoy, which is 15 miles away.
Deputies believe the people found at the scene could have detonated as much as 60 pounds of the legal substance. Tannerite is used for small explosive target shooting. No one was hurt.
