Police say hundreds of volunteers have turned out to help search for a Utah teen last seen Tuesday night.

Volunteers gathered at a Mormon meeting house to get directions on where to search for Brooklyn Gittins, who was last seen by family members Tuesday night in her bedroom, Fox13Now.com reported.

Investigators found no evidence of a forced entry, and family believe the 13-year-old may have run away. Authorities consider her endangered. 

Police say Gittins was wearing a gray t-shirt with a pink U of U logo and black pajama-style pants with a Scottish dog design. Gittins left home without shoes, a coat or her eyeglasses.

“Brooklyn, if you’re listening, please come home. We want you back Brooklyn. We need you to come home. We’re not mad, nothing will happen,” Craig Hiller, Gittens’ grandfather pleaded.

Police say they have contacted her friends, but she has yet to make contact with anyone, Fox13Now.com reported.

“We have the DPS helicopter and canine units canvassing the area. We’ve also had ground searches,” Sheriff Jim Winder told Fox13Now.com

Unified Police Lt. Justin Hoyal said Gittins has run away once before, and there is concern about a cold storm in the forecast.

"We're concerned with how she was dressed," Hiller told Fox13Now.com.

Gittens is described as 5-ft tall, 110 pounds with blonde hair and blue eyes. Police believe she is not wearing shoes.
