Marconi was a 20-year veteran of the force.

Authorities responded to the scene at 11:40 a.m. on West Nueva Street and Santa Rosa Street, SAPD Chief McManus said.

McManus said Marconi pulled over a vehicle outside of the Public Safety Headquarters. While he was inside his vehicle writing a ticket, a black vehicle pulled up behind him.

The driver of that vehicle got out, walked up to Marconi’s driver-side window and shot him in the head, McManus said.

Then the suspect reached into the window and shot Marconi a second time, he said.

The suspect then got back in his car and pulled away. Police believe the suspect’s vehicle was a 2009-2015 black Mitsubishi Galant with custom rims.

Police said Marconi was pronounced dead at San Antonio Military Medical Center around 12:30 p.m. Sunday.

McManus said the suspect is a black male around five-foot-seven to six feet in height, wearing a gray sweatshirt and black baggy pants. The suspect also has a beard.

Police said they do not know what the motive for the shooting was but are looking into every possible reason.

Chief McManus said in the press conference that they do not know if there was a connection between the car Marconi stopped and the shooter.

Until further notice, SAPD officers won't conduct traffic stops alone. They must have cover, said McManus in the press conference.

This is a capital murder case.
