The death of Héctor Rusthenford Guerrero Flores, known as Niño Guerrero, leaves Yohan José Romero, alias Johan Petrica, as the final founding leader of Tren de Aragua still at large.
Guerrero was killed in June 2026 during a joint US‑Venezuelan operation near Las Claritas, a gold‑mining centre in Bolívar state where he had taken refuge. His co‑founder, Larry Amaury Álvarez Núñez, alias Larry Changa, continues to be imprisoned in Colombia.
Petrica possesses the credentials to assume leadership. His criminal career began within Venezuela’s prison system; at Tocorón prison he, Guerrero, and Changa helped found Tren de Aragua, a gang that grew far beyond prison boundaries.
Prior to the recent military incursion that killed Guerrero, Petrica’s power base remained robust. Since 2017 he has headed Las Claritas Sindicato, one of southern Venezuela’s strongest mining syndicates, which controls a strategic enclave in Bolívar state that houses one of the world’s most lucrative gold deposits. Under the syndicate’s rule, artisanal miners, merchants, sex workers, cooks, and other service providers were compelled to pay taxes or surrender a share of their earnings.
The recent US‑Venezuela military deployment that killed Guerrero is likely to have disrupted longstanding arrangements between the Venezuelan government and the mining syndicate that permitted it to operate with relative impunity.
Assuming control over the Las Claritas stronghold will be challenging, and will also be essential for seizing Tren de Aragua’s broader regional operations.
Tren de Aragua has faced increasing pressure since Venezuelan security forces raided Tocorón prison, its historic headquarters, in 2023. Across South America, authorities have arrested leaders, dismantled cells, and weakened the group’s previously expanding transnational network. The United States has targeted Petrica, sanctioning him in 2025 for overseeing Las Claritas’ illegal mining activities and trafficking military‑grade weapons used in Venezuela. No arrest or death of Petrica has been reported since they entered his mining domain, raising suspicions that he evaded capture.
Consequently, Petrica is both a fugitive and a likely successor—a mining boss with deep Tren de Aragua roots tasked with leading a fragmented criminal organization.
