A few years back, a woman(don't remeber her name) drowned her two baby boys so she could be with her lover. She went on the air with tear filled eyes claiming she had been car jacked by a black man, and "please return my babies to me unharmed" all the while she new they were dead.
Perhaps you remember the Terry Anderson incident at Northridge Mall in Milwaukee. He stabbed and killed his wife, then superficially stabbed himself, and claimed they had been attacked by(memory cloudy here) at least one black man.(Interesting note: Terry was imprisoned with Jeffrey Dahmer, and both were killed in prison at the same time by the same inmate.) The latest incident is the Scott/Laci Peterson incident. He went fishing, then his wife disappeared. (Yeah, right!)
Here's a little story... I'm a dumb criminal, and I just reached the point where I want to kill my girlfriend who is 300+ miles away. I know that if I am getting a call from her on my cell phone, I will provide an alibi for myself. So I drive the 300+ miles, dispatch my girlfriend, grab her cell phone and call my cell phone. Alibi established(remember, I described myself as a dumb criminal.).
It's just a thought. But with press being replete with stories like this - the "I am so broken up because of my loss, please help me...oops, I'm the guilty party kind of stories - I too am very suspicious of the boyfriend. In the end, this has got to be very hard for her family and friends, especially if they know that, statiscally, people who go missing under these kind of circumstances are usually killed within the first 24 hours. (I remember Lori Depies, too. That was a sad case. I still think her boyfriend did it.)
