A Topeka man was sentenced Monday to 13 years in federal prison for robbing a Valero gas station and shooting the clerk.

U.S. Attorney Barry Grissom says Corey Eugene Johnson, 41, pleaded guilty to one count of robbery. In his plea, he admitted that on July 28, 2013, he robbed a Valero gas station at 1161 S.W. Gage in Topeka.

In his plea, Johnson admitted he was carrying a .40 caliber handgun when he entered the gas station and demanded money from the cash register.

Seeing a customer at the counter, Johnson ordered him to the floor and put his foot on the customer’s head. When a clerk refused to turn over money from the cash register, Johnson shot the clerk several times. Then Johnson ordered the customer to open the cash register. Johnson fled the store in a black Monte Carlo. Police found the wounded clerk, who was taken to the hospital and survived the shooting.

In June, co-defendant Shawn Michael Sneed, 22, Topeka, Kan., was sentenced to 84 months in federal prison.
