WARNING: Graphic content. Newly released surveillance video taken at the Elgin Middlesex Detention Centre in London, Ont., shows Anthony George beating his cellmate Adam Kargus to death on Unit 6 and then dragging the body into a common shower area the next morning, without any of the jail guards noticing. George, 32, from Kettle Point First Nation was sentenced to life in prison with no possibility of parole for 10 years on Oct. 7 for the 2013 death of Kargus, 29. The night Kargus died, throughout the beating, which lasted about an hour, George can be seen through the window, punching, kicking, stomping and choking Kargus while the inmate's face is pressed against the glass. During the attack, the other inmates can be seen banging on the glass of their own cells, some of whom were cheering George on, while others were trying to get help for Kargus. No guards responded, even though it was caught on a closed circuit camera. The next morning, George can be seen on the video leaving his cell with Kargus's body wrapped in a bedsheet and drag it to the jail's shower area. Guards finally discover Kargus's body at around 10 a.m. on Nov.1 and called paramedics, but by then Kargus was already dead.
