CHANDLER, Ariz. -- Police on Monday released the 911 call that led to the arrest of an Arizona woman suspected of trying to kill her hospitalized husband by injecting fecal matter into his IV line.
The call came Friday afternoon from the Chandler Regional Medical Center's head of security.
Hospital staff said they found Rose Mary Vogel tampering with the IV line and saw a brown substance blocking the tube.
When it was searched in the hospital, Vogel's purse contained a total of three syringes, including two with a clear liquid, police said.
Police documents said Vogel, 55, is a retired registered nurse who formerly worked at the Chandler hospital.
On the 911 call, the security supervisor said hospital staff didn't see Vogel inject the fecal matter into the IV line, but she was the only person in the room when the tampering occurred.
``She was in the room, and she's a former nurse and she was playing with the IV pump and everything else,'' the unidentified male supervisor said.
Police said a hospital laboratory test identified the substance as fecal matter. and a trace amount of a brown substance also was found in the needle of an otherwise empty syringe found in Vogel's purse.
Vogel, of Sun Lakes, is being held on suspicion of attempted first-degree murder and vulnerable adult abuse.
Police don't have a possible motive yet. Vogel declined to be interviewed by police and asked for an attorney after her arrest.
The incident occurred after 66-year-old Phillip Vogel had undergone a heart procedure. Police said Monday that he remains hospitalized, but his condition wasn't immediately released.
