Woman tries to kill hubby with poo

65-year-old Rosemary Vogel, 65, from Arizona, US, faces an attempted murder charges after cops say she put faeces in her husband's IV line and tried to end his life.
Her 66-year-old husband was already in critical condition as he recovered from heart surgery at the Chandler Regional Medical Center.
But his devious wife couldn't wait for nature to take its course, cops say.
Instead, she somehow got poo into a syringe and appears to have inserted into the man's IV, according to KTVK-TV.
Emergency alarms went off around 1:30 p.m. Thursday and responding nurses found the woman holding the IV bag. 
The nurses saw a brown liquid in the bag and immediately pulled it from the man's arm and went to get help.
When the nurse returned, Vogel was trying to empty the poo-soaked bag into a trash can but was stopped.
Later tests on the brown substance returned positive for faecal matter — but it's unclear whose it was or how Vogel did it.
Cops also don't have a motive yet.
"This is the first that I've heard where faecal matter has been injected into an IV system," Sgt. Joe Favazzo of the Chandler police told KTVK.
Cops also found three syringes in the woman's purse, including two filled with fluid and a third filled with faeces, cops said.
"The safety of our patients has always been and will continue to be an utmost priority at Chandler Regional Medical Center," the facility said in a statement about the incident.
The critically ill man is expected to survive the poo attack and his wife is behind bars in lieu of a $100,000 bond.
She also faces a vulnerable adult abuse charge.
"He's in his recovery process not only from his medical procedure, but from this attempt on his life," Favazzo told the TV station.
