On December 1, 2021, 22-year-old Sergio Maas was shot and killed in his apartment at the Spanish Village apartments on Sumter Drive near Bachman Lake in Dallas. Maas, described as Hispanic, was found in his living room with multiple gunshot wounds shortly before 4 a.m. He and another person in the apartment heard noises coming from the parking lot that they thought were drilling or a weed eater; Maas went to his balcony after seeing people around his silver Toyota Sequoia, activated his car alarm, and was then struck by gunfire after someone said die dog followed by 3–5 shots.

Investigators say the shooting was connected to a catalytic converter theft: Maas s vehicle had its catalytic converter cut out even though the car itself had not been broken into. Police report video evidence and shell casings recovered in a nearby backyard tied suspects to the scene, and cell phone data reportedly linked others to the offense. One man, Juvencio Solorzano, was identified as the likely shooter. Eighteen-year-old Isabel Campbell was charged with capital murder and held on $2 million bond.

Anyone who knew Sergio, saw activity at the Spanish Village parking area that night, or has information about the theft and shooting is asked to come forward.
