ST. PETERSBURG — A would-be snatch-and-grab thief came out empty-handed after trying to rob a 75-year-old St. Petersburg woman Monday.

Marcie Rae Lee had slid behind the wheel of her car after shopping at the Publix on 34th Street N when a woman described by police as black, 5 feet 4 to 5 feet 6 and about 135 pounds approached her demanding the money in her hand.

The suspect implied she had a gun, police said, but Lee refused to hand over her cash. When the robber reached in and attempted to snatch it, Lee chomped down on her forearm. The suspect fled into a red SUV when Lee loosed her bite.
