The naked body of a 22-year-old Michigan woman who went missing while dressed as Poison Ivy after a Halloween party was found on Friday and police say evidence indicates it was a homicide. The Monroe County Sheriff's Office confirmed on Saturday the remains found on a 13-acre private property near a heavily-wooded site close to train tracks are those of Chelsea Bruck. The medical examiner's office in Wayne County used dental records to confirm the body is Bruck's. Chelsea Bruck (left) was last seen in Frenchtown Township, Michigan, while dressed as Poison Ivy (right) Investigators and volunteers had been searching for Bruck  and more than one million fliers were handed out . She was last seen on October 26 about 15 miles away from where the body was discovered in Ash Township . Bruck, of Maybee, disappeared after attending the party in Newport on October 26, about 15 miles away from where her body was discovered Friday in Monroe County's Ash Township. She was dressed as the fictional comic villain  at the party and was wearing a leaf-covered top and a dark purple wig. Her body wasn't clothed when workers found it while trying to free a dump truck from soggy soil. Chelsea's older brother Nathaniel said in a post on the Help Find Chelsea Bruck Facebook page: 'I want to thank everyone for their efforts. 'And while this may be the end of the search, it is also a new beginning; the beginning of the search for justice for my sister.' Monroe County Sheriff Dale Malone spoke to the media during a conference about the discovery of the body . Monroe County Sheriff Dale Malone said evidence collected at the scene indicated the death was a homicide, although a cause of death remains inconclusive, the Monroe News reported. He did not say if the police have any leads, but did say the property owner is not a suspect, according to the Detroit Free Press. Malone said at a news conference: 'Our thoughts and prayers are with the Bruck family. 'In all likelihood, the crime was committed at or near where the body was located.' He added the killer likely 'was familiar with the railroad tracks that are there'. Michigan State Police were called to investigate the area in Ash Township where the body was found Friday . The Poison Ivy costume was found about ten miles away at an industrial site near Flat Rock earlier this month. Investigators and volunteers had been searching for Bruck since she disappeared and more than one million fliers about the missing woman were distributed. A witness told police about seeing Bruck in her costume around 3am the day she vanished, walking in the direction of where cars were parked. A man was with her. He was described as having dark hair, a thin mustache and facial hair. Witnesses said he wore glasses with a black hoodie. The cause of death could take up to a month to be determined due to the advanced decomposition of the body. Family and friends turned to public prayer in Monroe, Michigan last October after Bruck first went missing .
