Medical Examiner: Chelsea Bruck died of blunt force trauma

The Wayne County Medical Examiner has released the cause and manner of death for Chelsea Bruck. They say she died from blunt force trauma to the head.

Officials announced Friday night they had made an arrest in her case.

Bruck, 22, of Maybee Michigan, attended a 2014 Halloween Party Oct. 25 at a private residence with hundreds of others on Post Road in Monroe County's Frenchtown Township. Two days later the sheriff's office took a missing persons report from her family.

The party was the last time Chelsea was seen alive. Countless searches for her turned up nothing until April 2015 when investigators say fabric from her hand-made Halloween costume of comic villain Poison Ivy with green leaves was recovered in Flat Rock.

On April 24 of 2015 Chelsea's decomposed body was found in a wooded area.

The sheriff's department said in their news conference on Friday that their suspect knew details that only the killed would know.

A 27 year-old Newport man is in custody and is being held in the Monroe County Jail. He is expected to be arraigned later Monday afternoon. Officials have not yet made his name public.
