The gunman in a September 2014 “commando-style'' raid and murder in northern Kent County lost a bid to have his conviction and mandatory life sentence overturned by the Michigan Court of Appeals.

A Kent County jury convicted Jaman Amr Parish of armed robbery and felony murder in the slaying of Brent Luttrell. Five co-defendants were also convicted and sent to prison for varying terms.

The assailants went to Luttrell’s home on Pinewood Street NE in Spencer Township looking for marijuana and $80,000. As they stormed the house, Luttrell jumped from a window to escape.

Luttrell, 34, was stabbed and shot multiple times. He was still breathing after being pushed from a fleeing car onto Lincoln Lake Avenue NE, but died a short time later.

In his appeal, Parish says that while he may have assisted in the Sept. 8, 2014 armed robbery, there wasn’t enough evidence to convict him of first-degree felony murder, which carries a mandatory life term.

In a three-page ruling, the Court of Appeals disagreed.

Video surveillance and testimony from a co-defendant that Parish admitted to shooting and stabbing the victim as he attempted to flee support the jury’s decision, the three-judge panel wrote.

A Kent County jury convicted Parish in May, 2015 following a six-day trial. He was sentenced in June 2015 to a life term. Parish is being held at the Oaks Correctional Facility in Manistee.
