BURLINGTON, Iowa (AP) -- Burlington police say no charges will be filed in the shooting death of a man who police say was shot by his girlfriend after he shot her.

Police say 22-year-old Terrell Miller and 28-year-old Jacqueline Williams, both of Macomb, Ill., were in Burlington on March 16 to visit friends.

Police say Miller shot Williams once in the forehead during an argument. Williams gained control of the gun during a struggle and shot Miller, hitting him several times.

Williams survived. Miller died at the scene. An autopsy showed he was shot six times in the head.

Police Chief Daniel Luttenegger says Tuesday the results of the investigation were turned over the Des Moines County attorney's office, which has declined to file charges.
