Does anyone believe Britany Murphy's husband is involved with her sudden death?

She died of cardiac arrest this morning. When her husband, Simon Monjack, and her got married back in 2007, and friend said that Monjack was a con artist. I don't know the details, but they believed he married her for money. Now she's dead, and it'll be interesting to find out how she died, and if he's at all involved with her murder. I know she just died this morning, and they don't know how she died until a coroner does the autopsy. I just found that interesting, about people calling him a con artist. I don't know if that was something that people believed up to her death, or if their perception of him got better after their marriage, but i found it interesting. It is sad, someone dying very young, especially someone who was a celebrity.
