CASTLE ROCK  — An inmate being tried for the second time for the 2002 killing of a Colorado prison guard will plead guilty in exchange for a life sentence.

Edward Montour's lawyer, David Lane, told The Denver Post ( ) Thursday that prosecutors offered to drop the death penalty in exchange for a guilty plea.

Montour is accused of killing Eric Autobee by striking him in the head with a kitchen ladle at Limon Correctional Facility.

Montour was serving a life sentence in the 1997 death of his 11-month-old daughter when Autobee was killed.

His lawyers argue that Montour was wrongfully convicted of his daughter's death and say that affected his mental health.

The guard's father opposes the death penalty and has protested prosecutors' decision to seek it.
