OMAHA, Neb. (AP) — The police chief of Nebraska’s largest city says an Omaha police officer killed in the line of duty was shot just above the top of her protective vest.

Omaha Police Chief Todd Schmaderer gave more details Thursday of the shooting that killed 29-year-old Officer Kerrie Orozco on Wednesday. The chief said Orozco and another officer had responded to a call for backup from officers who came under fire from the heavily-armed suspect.

Schmaderer says 26-year-old Marcus Wheeler fired on police who tried to arrest him Wednesday afternoon. Orozco and another officer soon arrived and chased after Wheeler, who turned and fired on them, too.

Orozco was hit, and died at a local hospital. Wheeler was also shot and killed. Schmaderer says Orozco did not fire her gun.
