From the Toronto Sun:
"How the pretty redhead’s path crossed with Strong’s is unknown and investigators are keeping their cards close to their chest.
But his troubled route to potential murder suspect was allegedly triggered by a split in 2016 with a girlfriend.
'His ex-girlfriend cheated on him and afterwards she moved in with me and my former roommate in Oshawa,' one source — who didn’t want to be identified — told the Toronto Sun.
The relationship came off the rails, the source alleged, because 'Adam was controlling and abusive, often choking her out and forcing himself on her tiny 100-or-so- pound frame.'
The Sun source described the woman as a timid wreck who frequented a local Tim Hortons for a break from 'the filth' and his 'watchful eye'"

To answer the question about other online profiles and postings, the same source indicates that "A man named Adam Strong also wrote reviews on fetish fiction on X-rated website RabbitsReviews.com, two four-star reviews were for tomes called Sex Addicts Anonymous and Tales from the Milk Tank Dairy Co."
