Tel-Chai Nation: Two Saudi sisters found murdered in NY

It can probably be guessed who's responsible for the shocking murder of two sisters from Saudi Arabia found dead in the Hudson river:

New York City investigators believe that the two sisters from Saudi Arabia whose bodies were found bound together with duct tape floating along the Hudson River last week were alive when they entered the water, two police sources told ABC News.

Detectives are checking to see if any surveillance cameras captured the moment Tala and Rotana Farea entered the river. They are also trying to determine whether either of them had met with any counselors or therapists in recent weeks, the sources said.

The deaths are being investigated as suspicious, and there has been no determination on whether they are homicides, suicides or accidents, the sources said.

The medical examiner's office will ultimately determine the causes of death as the investigation continues.

[...] The women were found lying on rocks near the river, fully-clothed, both wearing black jackets with fur trim and black leggings. There were no obvious signs of trauma, police said.

The bodies are believed to have washed ashore with the tide and stayed when the tide went out, police said.

On Saturday, police identified the bodies as those of Tala Farea, 16, and Rotana Farea, 22.

The younger sister, Tala, had been reported missing on Aug. 24, according to the National Center for Missing and Exploited Children. That was the last time the two sisters were seen in Virginia, two police sources told ABC News.

It's unclear when the women arrived in New York and where they were staying, the sources said.
