Earlier this week, a human skull and bones washed up on Rikers Island, and the city Medical Examiner's office has since been able to make a positive ID.

As reported, the human remains were confirmed to belong to Sierra Shields, a 30-year-old flight attendendant who has been reported as missing since January of this year.

Shields, a Chicago native, had been living in Astoria, and was last spotted leaving work at LaGuardia Airport on January 14, according to reports.

While the Medical Examiner's office has not confirmed or determined a cause of death, cops shared they fear the woman had committed suicide, judging off of a phone call she made to a suicide hotline before disappearing.

Following her whereabouts being unknown, her union, the International Brotherhood of Teamsters' Airline Division, put out a $10,000 reward for anyone with information regarding her location and condition.

At the time of this report, her family wished to abstain from issuing a statement to press.
