A caregiver in a Jerusalem retirement home was arrested this week on suspicion he murdered a 90-year-old resident by strangulation.

On Wednesday, the physician who pronounced the man dead was also summoned by police under caution to explain why she didn’t report the signs of violence to police, the Ynet news website reported.

The alleged homicide was reported by another worker in the retirement home.

According to Channel 10, the suspect gave conflicting testimony on the procedures he was performing on the man’s neck, saying at one point he was merely adjusting the man’s oxygen IV.

The victim was sent for an autopsy after which the caregiver was briefly released from custody, the TV report said.

But the caregiver was rearrested after new evidence emerged, with a court extending his remand on Tuesday by a week.

The TV report said police were investigating the possibility of euthanasia.
