Investigators spent years building a case around witness accounts, video, cellphone records and evidence tied to the theft that preceded Sergio Maas’ death.
DALLAS, Texas — The arrest of a man accused of killing Sergio Maas during a 2021 catalytic converter theft has brought a nearly five-year Dallas homicide investigation back into focus, including the evidence police used to identify a suspected shooter and another participant.
Juvencio Solorzano, 22, was recently arrested in Mexico by members of the U.S. Marshals North Texas Fugitive Task Force and returned to Dallas, authorities said. He has been booked into the Dallas County jail on a capital murder charge. Police accuse Solorzano of firing the shots that killed Maas, also 22, after Maas noticed people around his Toyota Sequoia in the parking lot below his northwest Dallas apartment on Dec. 1, 2021.
The case began shortly before 4 a.m. at the Spanish Village apartments on Sumter Drive. Dallas officers responding to a shooting call found Maas shot inside his residence. Police initially reported that the circumstances and motive were under investigation. Detectives later concluded that the shooting occurred as a group was removing the catalytic converter from Maas’ vehicle.
According to the investigation, Maas and another person inside the apartment heard a noise outside and looked toward the parking lot. Maas saw people around his SUV, took his keys to his third-floor balcony and activated the vehicle’s alarm. A witness told investigators that gunshots followed. Maas was struck by the gunfire, fell back into the apartment and died at the scene.
Investigators found that the Toyota had not been burglarized in the conventional sense, but its catalytic converter had been cut from the vehicle. Video evidence also supported portions of the account provided to investigators, according to earlier reporting based on an arrest affidavit. Police continued developing the case in the months after the killing as they examined evidence connected to people they believed had participated in the theft.
A major development came in 2022 with the arrest of Isabel Campbell. Police accused Campbell of being an active participant in the crime that resulted in Maas’ death. Investigators said cellphone data placed her in the immediate area at the time of the offense. Earlier reporting on the arrest affidavit also described electronic messages and photographs that investigators considered relevant to the case.
The investigation was also linked to evidence developed while Dallas police were working another case. According to the arrest affidavit described in earlier reporting, officers searching a residence found shell casings that investigators said matched ammunition used in the Maas shooting. Information obtained through a cellphone warrant provided detectives with additional material as they worked to identify those they believed were involved.
Campbell ultimately pleaded guilty to murder and is serving a 10-year prison sentence, according to court records cited by FOX 4. Solorzano, meanwhile, remained wanted. Dallas police publicly named him as the suspected shooter in August 2022 and asked for help locating him, warning at the time that he should be considered armed and extremely dangerous.
The search extended beyond the United States. Authorities determined that Solorzano was in Mexico, where the U.S. Marshals Service worked with Mexican officials to locate him. The Marshals Service said its North Texas Fugitive Task Force includes Dallas police officers and works with other agencies to find people wanted on serious criminal charges. Authorities said Solorzano was taken into custody without confrontation before being returned to Dallas.
His return gives Dallas County prosecutors the opportunity to move forward with the case against the man police have long accused of firing the fatal shots. The capital murder charge remains an allegation, and Solorzano is presumed innocent unless proven guilty. The reports reviewed for this story did not identify a trial date or provide further details about his next scheduled court proceeding.
