Warren Watson has been sentenced to life in prison without the possibility of parole - plus 334 years - for the rape and murder of Lakewood attorney Claudia Miller in 2013.
The 54-year-old man was convicted of several charges Tuesday, including first-degree murder, sexual assault, and aggravated robbery.
Prosecutors say Watson fantasized about attacking a female attorney who practiced family law and planned the crime for months.
Authorities say Watson pretended to be a doctor and used a fake name when he set up an appointment with Miller on March 2013. Miller was beaten and strangled and police found her body in a storage room at her office building.
Authorities arrested Watson days later in Caldwell, Idaho.
