An autopsy determined his death was related to an injection of an anesthetic, propofol.  Barbara Pasa was a nurse in the surgery department at MercyOne Centerville Medical Center at the time of Tim Pasa’s death.  Investigators say Barbara Pasa had bought a $200,000 life insurance policy on her husband.
