Police followed a five-block-long trail of blood to find a suspect in the attempted overnight robbery of a Des Moines convenience store. The two clerks at the Kum ‘N Go convenience store near the Drake University campus refused to give a robber any money.

The two clerks fought with the man, who had a knife. The would-be robber got stabbed in the stomach. He ran, but police followed the blood trail and found him in a nearby apartment. The suspect lunged at police with a knife, then jumped out a second-floor window.

He was taken to a Des Moines hospital for surgery. The man faces first-degree robbery, willful injury and resisting arrest charges. One of the convenience store clerks had a knife wound on his arm, but he was treated at the scene.
