Honestly I've read so many things about this over the years and remember it happening , I don't know what to believe. Do I think Kerr McGee had her snuffed ? It's possible, but it would be a lot of trouble for a nobody like her. Did .gov do that ? Again I don't think so as she wasn't that level of importance as an employee and that facility fell into the realm of "open secrets" it wasn't like she worked at a covert facility no one knew about doing work no one was going to know anything about . Besides there's a million ways to deal with someone like her which don't involve going to the effort of having to assassinate her and then cover it up.
