attacked officers inside the cell house. According to investigators, prison gangs directed the attack to challenge Warden Thaddeus Pinkney. Soon the local and state police arrived and fired eight rounds of tear gas into the prison yard. Prisoners set buildings on fire, causing other prisoners to get involved. After many hours, the troops got all inmates back into their cells. Lieutenant William Thomas and two correctional officers, Robert Conkle and Stanley Cole, were killed; three correctional officers, Danny Dill, Dale Walker and Sharon Pachet, were injured. The warden put a "deadlock" system into effect until October 16, 1978. Prisoners were not allowed to leave their cells for any reason. Their meals were brought to them; all recreational time and work assignments were cancelled. The prisoners were not allowed to shower until October. Family visits were banned until October 14, and they were not allowed to make phone calls to their families until September 30. The officials of the prison began a renewed search of prisoners for weapons on October 2 and ended October 13. The prisoners filed a complaint in the district court on August 31 stating the "deadlock" was longer than was needed to restore order and was having adverse effects on the prisoners' mental and physical health. The district judge decided to wait until after the "shakedown" of weapons search to make any decisions. After the shakedown, on November 3, the court ordered Pontiac Correctional Center to restore the family visitation hours and phone privileges as they were before the riot, as well as the meals, exercise and work times. The court also required the prison to provide two hours of yard recreation a week to the prisoners. Because of this riot, the prison instituted a policy of moving only a few inmates at a time in a line. As 1997, prisoners in the maximum security unit are kept in their cell 24 hours a day, with exception of days when they are allowed limited time for yard recreation, use of the law library, showers, and visits. By 2008, a general population of prisoners had been reintroduced to Pontiac Correctional Center. Inmates who are not in segregation status are given more time out of their cells, including social time on rec yards, in the gym, and at dining times. Protective custody and inmates from the medium-security unit may obtain jobs within the prison, ranging from cellhouse porter to
