[No Clip 2 was released with this press release.]
According to the Sheriff’s Office investigation, at approximately 4:30 p.m. on Thursday, Division 10 detainees Alvarado and Stevenson took control of their housing tier, covering the floor with soapy water. They obscured the fixed cameras on the tier before tearing them down completely.
A criminal investigation is ongoing and additional criminal charges are expected against both detainees.
Alvarado has been in Cook County Jail custody since April 2015 on a murder charge stemming from Cicero Police Department arrest. Stevenson has been in custody since September 2014 on charges of armed robbery and aggravated vehicular hijacking, stemming from a Skokie Police Department arrest.
In June, Alvarado was charged with battery against another detainee. Stevenson was charged in October 2014 and July 2015 with aggravated battery to a peace officer. In each incident, Stevenson punched a correctional deputy. In May 2016 he was charged with disarming a peace officer.
Sheriff Dart applauds the exceptional expertise and professionalism of his staff and reminds the public that the defendants are presumed innocent until proven guilty by the government in a court of law.
