OMAHA, Neb. (AP) — Police are investigating a shooting that killed a 2-year-old girl and 22-year-old woman and critically injured three other women in northwest Omaha.

Officer Michael Pecha says the victims were shot in an apartment complex around 11 p.m. Sunday.

The victims who were alive when firefighters arrived were taken to two local hospitals. The others were determined to be dead on the scene.
