LAS VEGAS — A twice-convicted killer who wants to die rather than spend his life in prison was about an hour from eating his final meal Wednesday when he found out a Nevada judge had indefinitely delayed his execution after a pharmaceutical company objected to the use of one of its drugs to put someone to death.

Instead of carrying out what would have been the first execution in Nevada since 2006 and the first in the U.S. using an untried combination of three drugs, state officials must now reassess their options.

Scott Raymond Dozier, 47, was put on suicide watch as a precaution while officials planned a psychological evaluation at the state prison in the remote northeastern city of Ely before he returns to death row. Dozier was also placed on suicide watch after his execution was postponed in November.

Dozier was sentenced to death in 2007 for robbing, killing and dismembering 22-year-old Jeremiah Miller at a Las Vegas motel in 2002. His decapitated torso was found in a suitcase.

In 2005, Dozier was sentenced to 22 years in prison for shooting to death another drug-trade associate.
