PHOENIX (AP) -- A Phoenix businessman accused of plotting to kill his wife over a contentious divorce has been sentenced to eight years in prison.
Maricopa County prosecutors say 75-year-old Fred B. Knadler was sentenced Friday.
He pleaded guilty last month to attempted kidnapping.
Knadler is owner of Arizona Shower Door Inc.
He was arrested in January 2012 after he allegedly conspired with and paid one of his employees to kill his wife and bury her body in the desert.
Phoenix police say Knadler allegedly wanted to avoid losing millions of dollars in a divorce.
Investigators say Knadler allegedly gave Patrick King a cash down payment with the promise of an additional $10,000 when the job was done plus an additional $10,000 each year he maintained his silence.
King went to police.
Police said Knadler later tried to hire someone to kill his wife and King.
Knadler's wife told the judge that she is concerned for her safety.
"I fear for my life on a daily basis," Libia Knadler said. "My life has been transformed to a life of worry, fear and living in an emotional prison."
King said he also lives in fear and is afraid for the lives of his family.
"He chose from jail to hire somebody to kill me and that's when I was with my family," King told the judge.
Knadler's sons also addressed the judge during sentencing.
"My father has never committed a crime -- he waited until he was 75 to commit his first crime," said his son, Paul Knadler. "He's not the monster that the defendants are picturing him to be."
His sons said they believe diabetes affected their father's judgment.
