Batavia, N.Y. -- A woman was found guilty of punching a Walmart cashier.
Jacquetta Simmons, 26, was convicted of second degree assault for attacking 70-year-old Grace Suozzi at a Batavia Walmart on Christmas Eve last year.
Prosecutors say Simmons became angry after Suozzi asked to see Simmons' receipt.
Simmons could face up to seven years in prison after being charged under the state's "Granny Law." The law makes it a felony to injure someone 65 or older if the defendant is at least 10 years younger than the victim.
Simmons will be sentenced in November.
