Watch: San Antonio Cop Benjamin Marconi Shot in the Head in Broad Daylight, Search for Suspect Ongoing

McManus described the suspect as being a Black male between 5 feet 7 inches and 6 feet tall. After shooting Officer Marconi, the suspect — who McManus said possibly has a beard — got back into his car, pulled around the officer's vehicle and drove through the police headquarters' parking lot.

Marconi was pronounced dead at the hospital. 

“This is everyone’s worst nightmare,” McManus said. “It’s always difficult, especially in this day and age where police are being targeted across the country and hopefully we’ll solve this one real quick.”

Currently, Chief McManus said there is no clear motive for the shooting. However, investigators are reviewing video footage of the incident. The shooting did not immediately appear to be related to the traffic stop, McManus said. Yet, it does seem similar to police ambush shootings that have occurred earlier this year in Dallas, Baton Rouge and Des Moines.

“We don’t have a motive. There are a couple of different angles that we’re looking at,” McManus said.

No suspect has been obtained yet and police warn the public that he is still at large and considered dangerous.
