A Saskatchewan man who videotaped himself sexually assaulting a woman — providing the Crown with a key piece of evidence — has been sentenced to 30 months behind bars.

A Tisdale judge recently dealt with the case of Robert Sawchuk, 55, who sexually fondled a woman he was acquainted with while she was sleeping.

Court heard the woman used morphine and Sawchuk was her supplier.

In June 2012, he went to her house while she was sleeping on the couch.

With his cellphone camera running, Sawchuk touched her breasts, unbuttoned and unzipped her pants, placed his fingers under her shirt and touched her thigh near her crotch.

The woman, who is in her 20s, woke up to see Sawchuk overtop of her, holding his cellphone.

She fled to another room and Sawchuk left her home.

Months later, police seized the cellphone as part of a drug raid on Sawchuk's home.

The video had been erased, but police were able to recover it. It showed the assault, with Sawchuk visible in part of it.

Sawchuk pleaded guilty to sexual assault late last year and was sentenced on Feb. 4.

The Crown contended that he wanted to keep the video as a trophy, but the judge said that wasn't proven to her satisfaction. 

Judge Inez Cardinal noted the Sawchuk has more than 30 convictions on his record, including one for sexual assault in the 1980s.

With time already served, his net sentence is 23 months.
