SAPD Chief William McManus said the shooting occurred on the south side of SAPD headquarters, at 11:45 a.m. where the officer, identified as Detective Benjamin Marconi, 50, was issuing a traffic citation. As he did so, a black vehicle pulled up behind the officer’s unit.

A photo showing a person of interest was leaked on Facebook around 4:30 p.m. Sunday afternoon. San Antonio police confirmed the authenticity of the photo Sunday evening, and released a statement saying the person could have information on the slaying of the detective.
