As a teenager almost 20 years ago, Jeffery Christian was sent to a juvenile detention center in southern Illinois. He was abused by multiple staff over the course of several years, starting just a few days into his detention. According to a lawsuit filed last week in the Illinois Court of Claims, his mother reported at least some of the alleged abuse to leadership but no one followed up. He is one of more than 90 people who sued the state last week, saying they were abused by employees when they were in juvenile detention, some as young as 12 years old. It is the latest in a flurry of legal cases around the country claiming similar sexual misconduct by employees of facilities housing children charged with a crime. The U.S. Justice Department on Wednesday announced an investigation into Kentucky's youth detention facilities. Since the start of the year, there have been lawsuits filed in at least four states, including the one in Illinois. The men and women in the lawsuits allege very similar abuse. Some say they were raped. Others say they were forced to perform oral sex or were inappropriately touched by employees. Some say they were given rewards, like special snacks or extra recreational time, if they complied; others say they were punished for refusing. According to the Sentencing Project, a research and advocacy group, recurring abuse has been documented in state-funded juvenile detention facilities in 29 states and the District of Columbia.
