Rose Mary Vogel of Sun Lakes was arrested Thursday on suspicion of attempted first-degree murder after a nurse found the 65-year-old handling her husband's IV line, which was found to contain a brown substance, police said.
A hospital lab test identified the brown substance in the IV line 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, police said.
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 is a retired registered nurse who formerly worked at the hospital, Chandler Regional Medical Center.
Investigators plan to conduct forensic tests on all the materials involved over the next week or two, police Sgt. Joe Favazzo said However, the hospital had to test the brown substance in the IV line immediately for treatment purposes.
"The lab came back with fecal matter," he said.
The incident occurred after the 66-year-old man had undergone a heart procedure. He's expected to survive that, as well as the alleged attempt on his life.
Police don't know a possible motive. Vogel declined to be interviewed by police and asked for an attorney, but Favazzo said he didn't know whether she has one yet.
