Jenn:

Maybe a shot in the dark?

It's around a 6 hour drive from Toronto, Ont. to Columbus, Ohio.

Besides Brian Shaffer's disappearance looking more and more like an inside job, I don't think it would take much to find out if Bruce McArthur had crossed the border.

He'd have been around 53 at the time...would not fit in with the crowd, he preyed on gay men, but a 'rufie' in Brian's drink and a quick exit out the back door would be the only possible point of his egress?

Not hard to buy the cooperation of a waiter or other employee.
