BILLINGS - A repeat sexual offender convicted of burglary and attempted rape was sentenced Monday to life plus 100 years in prison with no parole.
District Judge Gregory Todd said the lengthy sentence stemmed from 53-year-old David Gunderson's record of committing sexually violent crimes and a psychologist's conclusion that Gunderson would not benefit from sex offender treatment. His sentences will be served consecutively.
"In essence, you are an incredible danger to the public and women in particular," Todd told Gunderson. "And you are a danger whenever and wherever you are outside prison walls."
Gunderson was convicted in February of entering a 23-year-old woman's apartment last spring and attacking her as she slept.
His criminal record began when he was sent to a youth detention facility for molesting a child. In 1973, when he was 19, Gunderson was convicted of felony lewd conduct with a child and was sentenced to prison. In 1985, he received a prison sentence of 20 years with 10 suspended for his involvement in a stabbing.
Gunderson was convicted in 1994 of raping a teenager and was given a 20-year prison sentence with five years suspended. He was released on parole in May 2007, about a month and a half before he attacked the 23-year-old woman in her Billings apartment.
