The 1971 shooting of Dallas County and Ellis County Sheriff's Deputies (also known as the Trinity River Massacre) occurred on February 15, 1971, when Rene Guzman and Leonardo Lopez abducted five law enforcement officers in West Dallas, Texas, killing three officers and injuring one at a site near the Trinity River. One deputy was able to escape the shooting and call for help. Guzman and Lopez were suspects in a burglary in Ellis County, Texas, and the officers were obtaining consent-to-search forms when they were abducted.
