This man has asked to remain anonymous but will speak to New Hampshire police.
He said at the time, Bill seemed to be in a very dark place and would go drinking practically every night after work at a place called The Bottom Line. His favorite drink, gin & tonic. This coworker got to know him well and considered him a friend. One day, after some drinks, he says Bill turned to him and said, "We're good friends, aren't we? Like best friends?" He said, sure. Then he claims Bill said, "I would help you bury a body. Really. I'd help you bury a body. That's how good of friends we are."
"I took it as a sincere moment," this man says. "At the time I brushed it off because he'd been in the military. I figured he'd seen casualties."
He says another time Bill told him how he'd go on the news to talk about Maura so that he could use it to pick up women. That he could play the depressed former boyfriend part and it worked very well.
He was there the day Bill was forced to resign his job at Ray Group after a woman said he sexually assaulted her in the office. They allowed him to resign instead of being fired. The executives agreed that they would leave it up to the woman to go to police. This woman can still go to police, actually, as the statue of limitation has not expired. I believe she is currently weighing that option.
In a related note, I just received a massive amount of information and names through a Globaleaks contact. There are more women with claims against Bill.
