An Ottawa man accused of drugging and sexually assaulting 14 women says it's likely his girlfriend committed one of the assaults because he says he passed out on the night when the alleged crime took place.

Philip Wilson, 33, has pleaded not guilty to 45 charges, including sexual assault, administering a noxious drug, drug trafficking, theft and procurement.

The accused was also charged with aggravated assault after his girlfriend was sent to hospital bloodied, unconscious and suffering from a fractured vertebra in March 2015. She was 28-weeks pregnant and lost the baby the next day.

Accused claims he passed out

Wilson testified Friday in the judge-only Ontario Superior Court trial that on the night of Aug. 1, 2014, a woman he'd known for about two years — who can't be identified due to a publication ban on her name — came to the apartment he shared with his girlfriend to buy cocaine.  

He told the court it wasn't the first time he and the woman had together consumed GHB, also known as the date-rape drug. GHB is one of the drugs the Crown alleges Wilson surreptitiously gave multiple women before sexually assaulting them.

That night the woman willingly took a drink with GHB added to it, but Wilson told the court he took a large dose and that things were "getting foggy."

Wilson said he passed out. He continued that when he woke up he saw the woman also passed out on the couch, but insisted she was clothed.

The woman appeared to have wet herself and he said he told his girlfriend to clean it up. Then he said he went to bed, where he slept until the next morning. When he woke up his girlfriend said she had given the woman fresh clothes to wear, he testified.

Wilson denied removing the woman's clothing or taking any photographs of the woman on his mobile phone.

Phone had explicit photos of woman

Police seized the phone and recovered photos of the woman with her eyes closed and her breasts and genital area exposed. The woman told officers she had no memory of being sexually assaulted but woke up on his couch naked with a blanket over her.

When Justice Charles Hackland asked who took the photos if it wasn't Wilson himself, Wilson said he assumed it was his girlfriend.

"When you found photos that showed close-up shots of someone's genitals, did you talk to [your girlfriend] about them?" Hackland asked.

"I'm not sure if I had a conversation with her about it," Wilson replied.

Accused then sent photos to woman

Justice Hackland then reminded Wilson of the woman's testimony. She said he sent her images of her exposed breasts.

"What's that all about?" asked Hackland. 

Wilson testified it was about two months after the alleged incident when he was surprised to find the photos on his phone.

"I didn't remember taking those photos," he said, but he told the court he didn't delete them.  

He said he sent the woman the photos because they were engaged in "sexually charged texting." 

Wilson's testimony is scheduled to continue Monday.
