DOVER — Two people were killed in a police-involved shooting Tuesday at an assisted living center.

Delaware State Police said a staff member of Harmony at Kent was shot by a man who had been escorted out of the building.

Two troopers fired guns at the suspect, killing him, in the parking lot.

According to authorities, at approximately 5:25 p.m., troopers responded to Harmony at Kent Senior Living Center, at 1435 East Lebanon Road, following a trespassing report.

The preliminary investigation, police said, revealed the suspect, Arnold Azamar, 51, of Camden, was on the property visiting a female relative after having been banned from the facility for aggressive behavior in the past.

Police said Mr. Azamar, accompanied by his female relative, was escorted out of the building by staff member William Whitehead, 59, of Magnolia.

Upon exiting the building, police said, Mr. Azamar punched Mr. WHitehead and then ran to his vehicle and retrieved a handgun from within, police said.

Once armed, Mr. Azamar fired one shot into a male relative’s vehicle as they drove through the senior living facility’s parking lot and then shot Mr. Whitehead,  according to state police.

After shooting Mr. Whitehead, police said, Mr. Azamar remained by his vehicle alongside his female relative as troopers and officers from Probation and Parole, Wyoming Police Department and Dover Police Department arrived at the scene.

Troopers attempted to negotiate with Mr. Azamar, however, he walked away from his vehicle and raised the handgun, which prompted two troopers to discharge their firearms at him, police said.

Following the shooting, troopers administered first aid to Mr. Azamar and Mr. Whitehead until EMS arrived and transported them to an area hospital, where they were both pronounced dead, police said.

At one point more than 20 police vehicles were at the scene. The Delaware Department of Transportation was detouring traffic from the area.

 No one else was injured as a result of this incident.

Per Delaware State Police standard operating procedures, the involved troopers have been placed on administrative leave pending a use of force investigation conducted in conjunction with the Delaware Department of Justice.

Investigation continues and police asked anyone with information to call Detective D. Grassi at 302-365-8441 or emailing daniel.grassi@delaware.gov. Information may also be provided by contacting Delaware Crime Stoppers at 1-800-TIP-3333.
