I'd Call That a Disfiguring Weapon

Down in Rock Hill, SC, a man robbed a convenience store by threatening the clerk with a can of what he described as "sulfuric acid."

Detectives have obtained surveillance footage from the robbery, the report states. The robber is described as a white man between 40 and 50 years old, about 6-foot tall and 190 pounds. He has gray hair and a goatee and was wearing a dark hoodie and jeans at the time of the robbery.

Sounds like a homeless guy using his last can of beer to acquire money to buy more beer.
