I'll take that bet.
Let's make the stakes a donation to Free Republic and a public helping of crow on this thread.
The amount of the donation will entirely be up to the loser.
Deal?
Deal! If the coroner says suicide you donate to FR, if they say homicide I will. The odds are against you though. The best numbers I could find from the CDC show a suicide rate of 6.5 per 100k per year for young white women, a homicide rate of 3.2. The odds from the beginning greatly favor suicide. All at once she lost her job, her lover (a real jerk), and had to move back home, which is enough motivation for a suicide. She was a high achiever/big expectation type. If she chose suicide she's more likely than average to succeed. Also, we're talking about the DC police here, they couldn't find the body until it was handed to them. Even if it was homicide they're probably not smart enough to connect the dots. Good luck to ya!
