Baja California prosecutors arrested one suspect in the May 17 shooting death of 21-year-old Juan David Ballesteros Méndez, who was killed during what he believed was a test drive of a BMW he had listed for sale in Mexicali.
State Attorney General’s Office (FGE) prosecutor Rubén Alfredo Maximiliano Ramos Jiménez confirmed the arrest and said a judicial hearing to formally charge the detainee is expected within days. A second suspect remains at large.
Ambushed During a Test Drive
According to the FGE, Juan David had posted the BMW for sale and was contacted by two individuals posing as interested buyers. He agreed to accompany them on a test drive near the Jardines de la Progreso subdivision, a residential area in southeastern Mexicali.
During the drive, the two individuals ambushed Juan David and shot him dead. They fled with the vehicle, which authorities later recovered abandoned in a nearby neighborhood. Investigators have identified vehicle theft as the primary motive.
Family Pressure and Investigation Progress
The victim’s family had publicly criticized what they saw as a lack of progress in the case. Ramos Jiménez said prosecutors maintained contact with the family throughout the investigation. Juan David had worked in the used-car trade since he was 17 years old, making vehicle sales part of his daily routine.
The arrest comes as private vehicle sales remain common across Baja California. Online marketplaces and social media groups are the primary channels for buying and selling cars in Mexicali, where face-to-face meetings between strangers are a routine part of the process.
Safety Concerns for Private Vehicle Sales
This case is one of several recent incidents in Mexicali involving crimes tied to private sales of vehicles and other high-value goods. Buyers and sellers in the region typically arrange meetings through Facebook Marketplace or WhatsApp groups, often with little verification of the other party’s identity.
Law enforcement officials across Baja California have repeatedly urged residents to conduct private sales at police stations, banks, or other well-monitored public locations rather than in residential neighborhoods. Sellers should avoid riding in vehicles with unknown buyers and should share trip details with a trusted contact beforehand.
