San Antonio Police have released surveillance video showing the suspect in the fatal shooting of Detective Benjamin Marconi walking through the department’s headquarters prior to the ambush attack on the officer.

The suspect shot and killed Marconi on Sunday as he was writing a ticket in his patrol car during a routine traffic stop involving an unrelated vehicle, Police Chief William McManus said. The shooter fired into the car twice from outside the vehicle and then fled in a black car.

McManus said they are not yet sure why the suspect was inside the police department headquarters prior to the shooting, which occurred near the building, but they “have some ideas.”

A $10,000 reward for information leading to an arrest has been offered by San Antonio CrimeStoppers. “Please call Crime Stoppers at 210-224-STOP with any info,” police said.

McManus described the gunman as a black male, about 5’7″ tall, wearing a hoodie and baggy pants. At the press briefing, McManus said the gunman was clean shaven, but in a Facebook post the department said he had a beard.

Marconi, a 20-year veteran of the police department, was rushed to the San Antonio Military Medical Center, where he was pronounced dead, KSAT-TV reports.

McManus said investigators have not yet determined a motive for the shooting.

“Right now we are looking for a possible motive. We are looking for video footage that may help us identity this individual,” McManus said, according to the San Antonio Express-News. “It’s always difficult, especially in this day and age, where police are being targeted across the country.”

He called the shooting “everyone’s worst nightmare. You never want to see this happen.”

San Antonio Mayor Ivy Taylor offered condolences to the officer’s family and the members of the city’s police department.

“This type of crime cannot and will not be tolerated,” she said in a statement. “I ask for the community’s thoughtfulness and patience as the investigation continues.”

Marconi was the father of two children, who are in their 20s, and became a grandfather earlier this year. He shared a photo on Twitter with his grandson on Father’s Day:
