(01/24/19) - The Tuscola County prosecutor will decide if a Caro grandfather will be criminally charged after leaving a loaded handgun at a school.

"You just start counting the ways this could have ended badly, and you count for a very long time," said Prosecutor Mark Reene.

Reene said Kingston High School hosted a basketball tournament for elementary students over the weekend.

A couple watching their son play found the gun.

"Noticed an item, at first thought it may have been a wallet, appeared to be wrapped in a handkerchief. Picked it up and kinda set it back down, had seen the individual who had been there," Reene said. "They then looked at it again, made the determination that it was not a wallet and in fact was a loaded handgun."

The Tuscola County Sheriff's Office was called and they were able to use the gun's serial number to figure out who it belong to.

The 69-year-old Caro grandfather who left the gun behind realized he had forgotten it and returned to the school, but deputies had already arrived.

Reene said the man has a license to carry a gun, but Kingston High School is a weapon free zone.

Reene wants to stress that gun owners have an "extraordinary responsibility" adding it's not like "any other type of property".

"It's always important to keep in mind 99-and-a-half percent of gun owners and people who carry guns do so responsibly, but it's a huge responsibility. So why would you take it in to a school in that setting at an elementary school basketball tournament. But then if you're doing that, how do you not keep track of it," Reene said.

Reene expects a decision about possible charges very soon.
