Yeah, there was a story exactly like that here in Colorado @ a 24hr fitness in Aurora.Although I don't remember if the news said whether or not those people ( at least 2..) lock thier lockers or not; I can see how it could happen... at the 24 hr fitness we go to , the overnight person seemd to have alot of people visit him at 3:30a when we were there...you know, not dressed to work out, hanging out at the counter.... who knows what they were doing in the Mens locker room....
