Witness against Gary teen in mom’s slaying gets time served

A young man who was a key witness in the case against a Gary teenager accused of stabbing her mother more than 60 times has been sentenced to time served.

The Times of Northwest Indiana reported 18-year-old Matthew Martin was given his punishment Tuesday after pleading guilty in December to assisting a criminal. He’s been jailed for about 21 months.

Martin told police he helped hide the knife that then-15-year-old Chastinea T. Reeves used to kill her 34-year-old mother, Jamie Garnett, at their home in Gary in February 2017.

Martin told the court he’s “grown” and “changed things around” since his arrest.

Reeves, who is now 17, pleaded guilty to murder and was sentenced last week to 45 years in prison. She was charged as an adult.
