The FBI has joined the search for 13-year-old Sa’Wade Birdinground, who has been missing since October 6,

The Big Horn County Sheriff’s Office reported that Sa’Wade was last seen at her Garryowen home on the night of October 6. She was wearing a black mushroom hoodie, an anime t-shirt, basketball trunks, and purple slip-on shoes, and she likely had a black and purple Adidas backpack.

She’s also known to wear an elk tooth necklace.

“There have been no known contacts with her family or friends since she disappeared. Sa’Wade has been described as a quiet, kind and artistic child who likes to laugh. Sa’Wade is well liked by her peers and teachers. She has never run away from home or been in any serious trouble. Her disappearance from home is totally out of character for her, and her family is very concerned about her,” the FBI said in a news release, according to KULR 8.

FOX News Digital reports that the “Montana Department of Justice issued a Missing Endangered Persons Advisory,” following safety concerns.

Anyone with information on her whereabouts should contact 406-665-9798. The FBI stated that “any details, no matter how small, could assist in bringing her home safely.”
