Police in Texas say a San Antonio officer who was fatally shot was targeted because of his uniform.

Police Chief William McManus said at a news conference Monday morning that he thinks “the uniform was the target” in the shooting of Det. Benjamin Marconi Sunday morning.

McManus says “anyone (in a police uniform) who happened along was the target.”

Police are asking the public for help in identifying the suspect in the shooting. The man appeared at the San Antonio police headquarters about four hours before the shooting. Surveillance video shows a black man likely in his 20s dressed all in black.

McManus declined to explain why police believe this man shot Marconi, saying he didn’t want to jeopardize the ongoing investigation.
