OMAHA, Neb. (AP) — Authorities are investigating whether an Omaha police officer was correct to shoot a man after he stabbed two other people.

Police were called to a neighborhood in southeast Omaha around 6:30 a.m. Sunday to deal with a man with a knife.

Officers encountered a 38-year-old woman outside the home with critical injuries, and then they met the 42-year-old man with a knife.

During the confrontation, one officer fired her weapon and wounded the man. Then officers found a 63-year-old man with knife wounds.

Three people were taken to the hospital for treatment, but they are all expected to survive.

The police officers were not hurt. The officer who discharged her gun is on paid leave while the incident is investigated.
