Investigators say Shamar Blair, 17, robbed a woman and her son at gunpoint at a drive-up ATM Tuesday night.
It happened at the Bank of America branch on Veterans Blvd. in Port Charlotte.

The mother is shaken up, but otherwise fine, a family member told WINK News.

According to the Charlotte County Sheriff's Office, the woman pulled up to the ATM at around 8:40 p.m., when Blair came at her with a gun an ordered her out of the car.

The woman's 7-year-old son was in the back seat.

Instead of listening to her alleged attacker, the mother handed over the money she was going to deposit, plus an extra $200 withdrawal.

Deputies say Blair ran away with the cash, only to be found minutes later, hiding in trees near the bank.

Debbie Bowe, a spokeswoman for CCSO, said the mother did the right thing.

"Do what you need to do to come out safe and well," Bowe said. "Thats what she did."

Bowe said that while drive-up ATMs are generally safer than walk-up ATMs, sometimes dangerous situations cannot be avoided.

"The primary thing that people need to be aware of when they go anywhere -- if they're in a parking lot, or a bank or wherever -- just be aware of their surroundings," Bowe said.

CCSO said it still has not found the gun allegedly used in the attack.

Blair's grandmother told WINK News that if her grandson had a gun, it was a toy gun.
