It all started last Wednesday when firefighters found a body inside a burning home on Cypress Street. They investigated murder, and Monday, brought their suspect into the adult system.
He's 16-year-old Marcus Anthony Matthews, a Lansing student who lived near Mares. Police believe he was trying to steal her car. They also believe he used a weapon against her and then set her on fire.
He faces charges for felony murder, arson, and car theft. He's being held in a juvenile facility without bond.
