A member of a federal law enforcement task force fatally shot a suspect who allegedly became combative Tuesday afternoon during a confrontation at an Eastlake-area strip mall.

The officers were taking part in an undercover narcotics investigation at the shopping center in the 2300 block of Proctor Valley Road in Chula Vista at about 2 p.m. when one of a half-dozen suspects they had contacted became violent, according to police.

Fearing for his life, an agent opened fire, mortally wounding the threatening suspect, Chula Vista Police Capt. Lon Turner told reporters. Both men were taken to a hospital, where the suspect was pronounced dead.

The agent apparently suffered only minor injuries, said Mike Carney, deputy special agent in charge for Homeland Security Investigations in San Diego.

Following the gunfire, two of the suspects ran off, got into a car and sped away. After traveling a short distance, the driver crashed the vehicle and was taken into custody along with his cohort, police said.

Officers searched the mall where the altercation occurred and fanned out into surrounding neighborhoods, eventually taking another suspect into custody. Police asked residents and workers in the vicinity to shelter indoors pending further notice.

A fourth suspect was found hiding inside a vehicle’s trunk, according to reports from the scene.

Just before 8 p.m., police tweeted that their activity in the area had ended and residents could resume normal activity.

Authorities released few details about the operation that led to the violent encounter, other than to say it targeted drug traffickers.
