01 March 2012 :

Robert Henry Moormann, 63, white, was executed in Arizona for killing his adoptive mother, Roberta Moormann, 74, on Jan. 13, 1984.
Moormann is the first Arizona inmate to be executed with one lethal drug, pentobarbital, as opposed to the state's long-standing 3-drug protocol.
The switch was made after corrections officials realized Monday that one of the three drugs had expired. In doing so, they violated their own new written execution protocol by giving Moormann only two days' notice of how he would be put to death instead of seven days' notice, as stipulated in the protocol. Moormann appeared to move more than other inmates executed with the 3-drug protocol. Unlike the other inmates, who appeared to fall asleep immediately, Moormann kept his eyes open during the entire execution.
Arizona joins Ohio, Texas and several other states that last year made the switch to pentobarbital. Moormann becomes the 1st condemned inmate to be put to death this year in Arizona and the 29th overall since the state resumed capital punishment in 1992, the 5th condemned inmate to be put to death this year in the USA and the 1282nd overall since the nation resumed executions on January 17, 1977.
