SAN ANTONIO — Police are still looking for the suspect Monday morning who shot and killed 50-year-old SAPD Det. Benjamin Marconi outside police headquarters in downtown San Antonio on Sunday.

SAPD Sgt. Jesse Salame confirmed that investigators are still looking for Marconi’s killer, who is being described as a dark-skinned male, approximately 5 feet 7 inches to 6 feet tall, wearing a gray shirt and black pants.

Salame said the suspected shooter’s vehicle is a black Mitsubishi Galant with chrome wheels.

Marconi, a 20-year veteran of the police force, was a great guy who cared for his job and the people he worked with, Salame said.

The fatal shooting occurred at about 11:45 a.m. when Marconi was issuing a traffic citation to a driver. As he was doing so, a black vehicle pulled up behind the officer’s patrol car. The driver of the vehicle got out of the car, walked up to the passenger window of Marconi’s vehicle and fired one round into the car, striking Marconi in the head. The suspect then reached into the vehicle and fired again, striking Marconi a second time, according to police.

Crime Stoppers is currently offering up to $10,000 for information leading to the arrest of a suspect or suspects in the capital murder.

“Right now we are looking for a possible motive,” said SAPD Chief William McManus. “We are looking for video footage that may help us identify this individual.”

McManus described the situation as everyone’s worst nightmare.

"It's always difficult, especially in this day and age, where police are being targeted across the country," McManus said.

The last San Antonio police officer killed was Robert Deckard Jr., who died in December 2013.

Deckard, 32, was a seven-year veteran at SAPD who was shot Dec. 8, 2013 as he pursued two robbery suspects. The chase reached speeds of 115 mph, police said. Deckard died after 13 days in intensive care.
