Guerrero Correctional Institution
The Guerrero Correctional Institution ("Institución Correccional Guerrero") is a prison for men located in Aguadilla, Puerto Rico, owned and operated by the Puerto Rico Department of Corrections and Rehabilitation. With a stated capacity of 944 inmates, it's among the three largest prisons in the territory. The facility was first opened in 1986 as a Community Therapy mental health unit ("Comunidad Terapéutica de Guerrero") of the Puerto Rico Department of Health. It became a correctional facility in March 1997. As of 2008 about a third of its inmates were pre-trial detainees, and the others were serving  longer sentences at minimum security. From 2002 to 2008, some 53 Guerrero inmates died inside the institution, all but one of them pre-trial detainees, and 73% of them within their first week behind bars. An extensive report by the ACLU of Puerto Rico blamed the abuse of a horse tranquilizer, Xylazine, among inmates, and lack of appropriate medical attention and lack of accountability among prison officials.
