The elder of the two sisters whose bodies washed up along the Hudson River is last known to have lived in a high-rise apartment in Virginia, it has been revealed.

Rotana Farea's last known address was at the Skyline Apartments in Falls Church.

The 22-year-old and her 16-year-old sister Tala were found dead - their bodies bound together by duct tape - on the riverbank of New York's Upper West Side neighborhood last week.

Authorities believe the sisters may have died in a suicide pact, but questions continue to swirl about when they disappeared and how they ended up in New York.

Mystery continues to surround how the bodies of Rotana Farea, 22, (left) and her 16-year-old sister, Tala Farea (right) washed up along the Hudson River last week. They are pictured here in sketches released by the New York Police Department

The sisters lived in Jedda, Saudi Arabia before moving to the US with their mother, who lives in Virginia.

Rotana is last known to have lived in the Falls Church apartment with a man named Abdulsalam Farea.

Their relation remains unclear, as does whether Tala lived with them.

Family members claim the sisters' mother reported Tala missing two months ago, but called off the search after finding out she was in New York visiting her sister.

The National Center for Missing and Exploited Children said Tala was last seen August 24. The alert said she might be with her sister.

Fairfax police confirmed to DailyMail.com that at least one Farea sister was reported missing by family.

They said there was no reason to think the sister was abducted or in danger, which is why no images were released to the public.

Family members told Arab News that the two sisters had only lost contact with their mother a week ago.

They are insisting that the pair did not commit suicide and are waiting to find out the cause of death from the Chief Medical Examiner, which has not yet released findings from the autopsies.

Authorities received a 911 call at 2.40pm from a passerby who spotted the two bodies floating in the water off the city's Upper West Side neighborhood

The bodies were laying on rocks near the river when authorities arrived on the scene

Rotana and Tala were found fully clothed, wearing black jackets with fur trim and black leggings, when their bodies washed up near Riverside Park last week.

Their bodies were bound together with duct tape that was tied around their feet and waists. The pair were found facing each other.

Authorities believe the women jumped off the George Washington Bridge, their bodies floating six miles down the river before reaching Riverside Park.

A passerby called 911 at 2.40pm on Wednesday after spotting the two bodies, which were found laying on rocks by the river when police arrived at the scene.

Neither body showed signs of trauma.

The sisters' father has since arrived in New York following news of their death.
