EDEN PRARIE, Minn. — Police say an officer who shot a motorcyclist early Saturday morning may have done so negligently.

The Hennepin County Sheriff’s Office is investigating the shooting, where police say an Eden Prairie officer pursued a man on a motorcycle a short distance and accidentally shot him when the chase ended.

Police say the man was struck in the arm by the officer’s gunfire. Police have not said why the officer drew his gun and fired, or what started the chase. There have been no reports that the motorcyclist, whose name has not been released, was armed.

The sheriff’s office says the man is in their custody for fleeing from police, and is receiving treatment a local area hospital.

The sheriff’s office has not released the name of the officer suspected of negligently shooting the man, but are expected to release a statement Monday. The officer has not been charged with a crime.

WARMINSTER, Pa. — A family is set to receive $650,000 after successfully suing Warminster police for fatally shooting an 89-year-old woman.

Marie Zienkewicz was shot and killed in February 2013 while Warminster police attempted to apprehend an intoxicated man, Andrew Cairns, who was in an apartment above Zienkewicz.

The Philadelphia suburb will cover the expenses of the lawsuit, and is also slated to provide its police officers with more training, and to donate books in Zienkewicz’s memory to the local library.

Police say Cairns had earlier fired his gun during a dispute with his girlfriend, and had barricaded himself in his apartment for several hours before being taken into custody.

Cairns’s girlfriend, Deborah Silva, had gone to Zienkewicz’s apartment to escape. As Zienkewicz opened her door and reached out to allow Silva inside, police say an officer mistook her for Cairns and fired at her through a door, killing her.

Cairns was held responsible for the death and is now serving 14 to 30 years in a state prison. The police officer who shot and killed Zienkewicz was cleared of any criminal wrongdoing.
