GRAND RAPIDS, Mich. (WOOD) –- A man has entered a guilty plea in an August 2013 Grand Rapids murder.

DeMarco Marquis Carnegie, 28, pleaded guilty to first-degree murder in Kent County Circuit Court in connection to the death of 47-year-old Marie Nettles. As a result, prosecutors will drop an armed robbery charge.

Carnegie is accused of strangling Nettles. On Aug. 8, 2013, her naked body was found along the Plaster Creek Trail behind Ken-O-Sha Elementary School, not far from the intersection of 28th Street and Kalamazoo Avenue SE in Grand Rapids.

Just six days after Nettles’ body was found, police said Carnegie threatened a couple in California with a hammer and then robbed them.

He was serving an 11-year prison sentence for that crime when Grand Rapids police investigators named him a suspect in Nettles’ murder.

Carnegie was extradited to Michigan in February to be tried for the murder.

He’s scheduled to be sentenced on Sept. 3.
