Two Arizona sisters who were reported missing by their family in Switzerland died by assisted suicide, authorities say.
Lila Ammouri, a doctor, and registered nurse Susan Frazier flew to Basel, Switzerland on 3 February, and had been due to return to the United States on 13 February.
When they failed to show up for work at Aetna Health Insurance in Phoenix, friends and family appealed for help to find them.
Their deaths were confirmed by the State Department’s Bureau of Consular Affairs on 19 February, but no cause of death was given.
A spokesman for the Basel-Landschaft Public Prosecutor’s Office confirmed to The Independent that the sisters had died by suicide “within the legal framework”.
“The public prosecutor’s office of the Canton of Basel-Landschaft confirms that the two US women died during their stay in Switzerland. They both committed suicide – with the help of an assisted suicide organisation,” Michael Lutz told The Independent.
Mr Lutz said assisted suicide is legal in Switzerland “under certain conditions”.
“In the specific case, the on-site checks by the authorities revealed that the assisted suicide took place within the legal framework, so that the Basel-Landschaft public prosecutor’s office did not open a criminal investigation.”
Brother Cal Ammouri told Arizona’s Family last week that he had last spoken with one of his sisters a few weeks before they went missing, and didn’t know they had travelled to Switzerland.
“She didn’t tell me anything at all, not a thing,” he said.
“Everyday I check the mailbox and I wonder if maybe if they’ll get in touch with me somehow. I love them both and I want them to come back,” he told the news site.
According to an online profile, Dr Ammouri, 54, was a hospice and palliative care specialist in Flagstaff, Arizona.
She practised at Flagstaff Medical Center and was “board certified in Hospice Care and Palliative Medicine”.
After the two sisters were reported missing, friends and family suspected they might have been the victims of foul play.
Longtime friend David Biglari said the last text he received from Ms Ammouri had spelling mistakes that were completely out of character.
