'Mary said the shot gun went off "accidentally". Did the phone get unplugged accidentally? Did the reservations for her get away get made accidentally too? Did she accidentally write 17 THOUSAND dollars of hot checks for which she and Matt were to meet the authorities at the bank the day he was shot to talk about paying it back? (The last I knew, writing checks for money you knew you did not have was a crime but she got away with that too.) What would YOU do if you accidentally shot someone? Would you watch them bleed to death or would you call 911? Also, there was NO EVIDENCE of abuse and I contend there is a good chance Matt did not even know about the high heels that were used to prove his abuse. He is no longer here to defend himself as she trashes his name more and more.
