A 52-year-old man accused of filming and taking sexually explicit photos of his adult daughter while she slept was sentenced Monday to four years' probation.

As part of the terms of his probation, the man will also have to serve one year in the Pima County jail.

The man pleaded guilty to kidnapping for the purpose of sexual gratification in December 2012.

The Star is not naming the man to protect the identity of his daughter.

He was initially indicted in April 2011 on one count of sexual assault, one count of incest and three counts of voyeurism involving his daughter. He was also indicted on 26 counts of sexual exploitation of a minor involving another victim.

Defense attorney Rick Lougee told Pima County Superior Court Judge Christopher Browning there was no evidence that the man had sexual intercourse with his daughter, calling allegations that he did "merely speculation."

The man took provocative photos and videos of his daughter and did Internet searches for rape and incest, said Shay Beasley, a third-year law student working at the Arizona Attorney General's Office. The images were discovered by investigators working on an unrelated felony crime case.

The man's daughter and the other victim did not cooperate with the Arizona Attorney General's Office.

Lougee asked for probation for his client, citing a doctor's evaluation that he could be treated and because it was his first offense.

The man told the judge he was "terribly ashamed" and that he hoped his daughter would forgive him one day.
