On October 24, 2023, at about 5:06 p.m., officers responded to a shooting at a residence in the 11200 block of Mickelson Drive in southeast Austin. They found 28-year-old Joshua Steven Lopez Rivera with multiple gunshot wounds; he was pronounced dead at the scene. Rivera had been invited to the home by its occupants.

According to an arrest affidavit, 46-year-old resident Joshua Trezaratti said Rivera, who was dating his stepdaughter, had previously made unwanted sexual advances toward his wife and had been abusive to the stepdaughter. Trezaratti allegedly confronted Rivera with a shotgun after Rivera arrived, a physical struggle followed, and Trezaratti shot Rivera multiple times with a handgun. Trezaratti remained at the scene and was arrested; he was charged with first-degree felony murder and booked on an $800,000 bond.

Detectives noted Trezaratti did not say Rivera was armed or had threatened violence while at the residence. Austin’s Homicide Unit is investigating and has asked anyone with information to contact them. Did anyone in the area see Rivera arrive or witness what happened inside the home?
