The city’s medium-security jail has long been the subject of complaints and protests. In addition to its lack of air conditioning, residents have raised concerns about alleged abuse from guards and unsanitary conditions in the facility. It houses more than 760 inmates, most of whom have not been convicted and are awaiting trial.

A crowd of about 150 demonstrators gathered at the jail on July 21 to demand its closure. St. Louis police used pepper spray to disperse the crowd. Protesters damaged the exterior perimeter fence, and two officers were injured.

Addo said officials are looking into how to regulate the temperature with thermostats. He said the mayor’s office is still evaluating the best way to keep the place cool long term, but also is meeting with other agencies to try to reduce the jail’s population. Krewson’s office arranged a meeting with judges, probation and parole officials, and state and city corrections.
