Mich. woman, 22, missing since leaving Halloween party

MONROE, Mich. -- Authorities are asking for information about a 22-year-old woman who has been missing since attending a Halloween party last weekend in southern Michigan, reports CBS Detroit.

Chelsea Ellen Bruck, of Maybee, Mich., has been missing since the party early Sunday morning in Frenchtown Township, about 30 miles south of Detroit. Sheriff's officials said a witness had come forward, saying he had seen Bruck with an unknown white male.

According to officials, the male was of medium build, had medium-length dark hair, a thin mustache and some facial hair. He was wearing a plain, black hooded sweatshirt with no visible logo and black-framed glasses. A sketch was drawn up, according to CBS Detroit.

Bruck is described as a blonde-haired white female, around 5-feet-7 inches tall. She is reportedly 140 pounds and has a small tattoo of an anchor behind her right ear. She was last seen dressed in a "Poison Ivy" Batman costume with black yoga pants, green ivy leaf-covered shirt and a long dark purple wig.

Also, Bruck and the unknown man were reportedly seen walking toward parked cars outside the party. It is unknown whether they both got into a car and drove off, reports CBS Detroit.

Helicopters and ground search teams are searching near the area where the party was held. Bruck's family and friends are planning a search today for clues to her whereabouts, according to the Detroit Free Press. Her sister, Kassandra Bruck, also told the newspaper that the family is encouraging other people to share photos of Chelsea.

Investigators also wish to speak with anyone at the party who may have seen Bruck or recognize the unknown man.

Anyone who has any information about this case is asked to call the Monroe County Sheriff's Office at 734-240-7700 or Monroe County Central Dispatch at 734-243-7070.
