Prosecutor: DNA links man to Chelsea Bruck in Halloween party death

DNA taken after an arrest in an unrelated case led investigators to the man charged with killing a woman who disappeared from a Halloween party in southeastern Michigan in 2014.

Monroe County prosecutor William Paul Nichols says investigators benefited from a 2015 law that allows police to take DNA from people who are arrested.

Without the law, Nichols tells The Monroe News that Daniel Clay would "still be out there walking around." Clay was charged Monday with second-degree murder in the death of 22-year-old Chelsea Bruck.

State police told the sheriff's office that Clay's DNA matched DNA found on Bruck's Poison Ivy Halloween costume. He was arrested in May in the theft of tattoo equipment.
