SAN JOSÉ — 1986 · Serial Murder

"El Psicópata" — Costa Rica's Unidentified Serial Killer

UnsolvedSources: ALast updated: 14 October 2026

Between 1986 and 1996 at least 19 people, mostly couples and lone women found on isolated roads or near coffee plantations, were killed around Desamparados, Curridabat and Cartago, south-east of San José. The killer, dubbed "El Psicópata" by the press, was believed to use a long gun and to stalk his victims at night. Police and the OIJ questioned many people and requested FBI assistance, but no one was ever charged. The killings stopped after 1996. Although the file is effectively closed because the statute of limitations has expired, it is still debated as Costa Rica's largest unsolved series.
