A Columbus Division of Police officer shot and killed a man who authorities said would not drop a BB gun April 6 in the parking lot of Mount Carmel St. Ann's hospital in Westerville.

Police identified the mortally wounded man as 39-year-old Christopher L. Wade.

Officer Nathan Komisarek, a 14-year veteran, was identified by police as the officer involved.

It was the seventh officer-involved shooting this year, police said.

Per policy, Komisarek is on desk duty pending the outcome of an investigation by the Columbus Police Critical Incident Response Team.

Wade reportedly was experiencing "psychological issues" and had asked Westerville medics to transport him to St. Ann's, Columbus police spokesman Sgt. Rich Weiner said. The medical-transport request was recorded at 1:03 p.m. on the 6700 block of Garden Terrace Road.

Medics asked Columbus police to send an officer to accompany them in delivering him to the hospital.

After they arrived the hospital, Wade saw Komisarek and pulled what was believed to be a gun from a bag, according to Columbus police.

He allegedly refused several commands to get on the ground and refused to drop the weapon before Komisarek shot him, police said.

The weapon later was determined to be a BB gun.

Realistic-looking BB guns and toy guns are "something we have been dealing with for a long time," Weiner said.

Wade died at the hospital just before 2 p.m.

No one else was injured.

Officers from the Westerville Division of Police also were on the scene, along with several fire units.
