A woman known by community members as "grandma" in one Washington, D.C. neighborhood helped put a 15-year-old in the ambulance after he allegedly attempted to carjack her as she was leaving to go to chemotherapy.

The attempted carjacking occurred on Feb. 17 at around 8:30 a.m. in the 22nd St. Southeast neighborhood, according to the Metropolitan Police Department, which said the 15-year-old suspect entered the senior citizen's vehicle "demanding keys" to the car. Police say that the victim attempted to pull the teenager out of the car while yelling for help from her family.

The woman told WJLA that she told the teenager he wasn't taking her car.

"Next thing I know, he walked up talking about, 'give me your keys, I got a gun.' I said, 'baby, you better shoot me, because you’re not taking my car," the woman said.
