Robert Gleason

Robert Charles Gleason Junior (10 April 1970 - 16 January 2013) was an Irish man and prison inmate who killed two fellow prisoners in separate incidents.
Gleason murdered Michael Kent Jamerson in the USA in 2007, and was sentenced to life imprisonment. He appealed to the Department of Corrections to transfer his cellmate, murderer Harvey Watson, in 2009, as Watson's severe mental illness made it hard for Gleason to spend his life in a cell with him. However, this was refused, and Gleason responded by hog tying Watson, beating him and strangling him to death. Gleason vowed to continue killing until he was executed, and to prove this, he fatally choked robber Aaron Cooper through the wire fence separating their cells. Realising Gleason was telling the truth, authorities sentenced him to death.
Gleason waived his right to appeal and chose the electric chair as his method of execution. Gleason was executed by electric chair in 2013.
