The family of a 30-year-old Queens woman who has been missing for nearly a month is hosting a day of fasting and prayer on Thursday, Feb. 11. 

Sierra Shields was last seen around noon on Jan. 15 leaving LaGuardia Airport, where she worked, wearing a navy blue dress, police say. 

Shields, a flight attendant, was scheduled to fly that afternoon, but never made her flight, according to Pix11. She reportedly quit her job earlier that day. 

Her phone and wallet were found at her home. 

The Astoria resident is 5-feet, 7-inches tall, 160 pounds, with a medium build, medium complexion, black hair and brown eyes. 

The Shields family started a crowdfunding compaign in January to help in ongoing seach efforts. 

A Facebook group, Find Sierra Shields, and #FindSierraNYC are also being used to help find Shields.
