On the night of August 4, content creator César Gastélum was recording a livestream with two friends in a KFC parking lot in Culiacán's Tres Ríos neighborhood when two helmeted men on a motorcycle pulled alongside the group and opened fire. Gastélum died in front of an online audience watching in real time; his two companions walked away unharmed. Footage later reviewed by investigators shows the same motorcycle passing the location once before the gunmen circled back and seconds before the shots, one of Gastélum's companions can be heard warning, "Those guys scare me." Four days later, nobody has been arrested and no cartel faction has claimed the killing.
The Delivery-Driver Costumes
Gastélum and his two friends were dressed in the orange gear typical of food-delivery courier. That costuming briefly threw off the initial response: police first logged the shooting as the killing of a delivery worker before correcting the record once Gastélum was identified, according to Al Jazeera.
A heavy police and military response arrived within minutes of the shooting, and Culiacán's municipal force has since increased patrols through Tres Ríos, stopping motorcycles that lack plates or violate traffic rules, according to SDP Noticias. Even so, as of August 8, authorities have announced no detentions and released no official motive, a status confirmed independently by La Jornada. President Claudia Sheinbaum addressed the killing at her morning press conference, telling reporters, "We must find out why this deplorable homicide occurred," and calling for both the shooters and whoever ordered the attack to be brought in.
A Working Theory, Not a Confirmed Motive
Mexico's federal Security Cabinet says it's coordinating with Sinaloa prosecutors and is examining posts in which Gastélum referenced a faction of a criminal organization, though officials haven't named the group or offered further detail. That inquiry sits inside a larger, ongoing rupture within the Sinaloa Cartel, which split into rival blocs loyal to the jailed Chapo Guzmán's sons and to allies of the arrested elder leader Ismael "El Mayo" Zambada, a conflict that's simmered since September 2024, per Univision. Authorities have stopped short of tying the social-media angle to either faction directly, and beyond the abandoned delivery-worker mix-up, no competing explanation has gained official traction.
Some early coverage framed Gastélum's comedy-and-lifestyle brand as unconnected to Sinaloa's narco-influencer subculture — creators who build followings around cartel-adjacent wealth and imagery. That framing undersells the record. Gastélum ran a recurring sketch character built around a Sinaloan slang term tied to cartel culture, and he referred to himself using that same term in his own posts, according to Al Jazeera. In December 2024, he also posted a photo from the grave of Leobardo Aispuro, an influencer known as "El Gordo Peruci" who was killed that same month in a suspected cartel-linked attack, thanking Aispuro publicly for his advice, according to reporting relayed by RPP. None of that confirms a motive for his own killing — Mexican authorities have said he wasn't under active threat or investigation before August 4 — but it complicates any claim that his content sat entirely outside that world.
A Hoax Video Is Muddying the Timeline
An old clip of Gastélum apologizing to followers for "a joke that got out of hand" began recirculating online on August 5, stripped of its original date, and some viewers took it as proof he'd faked his death or that the shooting itself was staged. The Latin Times traced the video back to a prior, unrelated post and confirmed no footage or statement from Gastélum exists from any date after August 4.
Estimates of Gastélum's TikTok following number at roughly 600,000 with 116,000 Instagram followers and more than 16,000 YouTube subscribers.
An Echo of Valeria Márquez
Gastélum's death immediately drew comparisons to the May 2025 killing of Valeria Márquez, a 23-year-old beauty influencer shot inside her Zapopan, Jalisco, salon while livestreaming to TikTok followers. Moments before she was killed, Márquez told viewers, "Maybe they were going to kill me," after two men had shown up earlier posing as a delivery with a gift for her, according to Fox News. Unlike Gastélum's case, Márquez's killing has since produced an arrest: on July 30, 2026, Mexican special forces detained Ramón Ángel Álvarez Ayala — known as "El R-1," accused leader of a Jalisco New Generation Cartel-linked cell called Los Rs — on suspicion of ordering the hit after Márquez ended a relationship with his son, according to Dexerto. The same cell has also been linked to the November 2025 assassination of Uruapan Mayor Carlos Manzo in Michoacán, according to ABC7, though the alleged gunman and Álvarez Ayala's own son both remain fugitives.
Culiacán Isn't the Only City
Content creators have been shot dead in more than one Mexican state this year. In January 2026, trucking and travel influencer Isaac Efraín "Chakin" Valadez was found dead inside his vehicle in Ensenada, Baja California, hit by at least seven bullets in what police logged as an armed attack; no arrests have been made, and unlike the Culiacán and Zapopan cases, no cartel link has been officially confirmed, per reporting relayed by Yahoo. That same month, Culiacán-based creator Nicole Pardo Molina was abducted at gunpoint from a shopping-plaza parking lot in a carjacking captured on her own vehicle's cameras; the Sinaloa Attorney General's Office confirmed four days later that she'd been located alive and in good health, per ABC7. Mexico has seen at least 21 social-media influencers kidnapped or killed over the past five years, according to a tally cited by CBC News.
For now, the investigation into who killed César Gastélum, and why, stays open. Mexican authorities say ballistic evidence and surveillance footage are still under review, with no timeline given for an arrest.
