Matthew Phillip Brown, 30, of Middle River received a life sentence with all but 20 years suspended, for his role in the death of William "Ray" Porter. Porter was shot and killed by Walter Bishop at the Hess gas station on Joppa Road on March 1, 2010.
Prosecutors said Brown accompanied Bishop, the triggerman, who was driven to the gas station by Calvin Lee Mowers.
"Clearly the evidence showed he (Brown) was the least culpable of all the defendants," said State's Attorney Scott D. Shellenberger Friday.
Brown, who was found guilty of first degree murder, is the fourth defendant sentenced. Bishop has been convicted and sentenced to two consecutive life sentences plus 20 years for his role. Susan M. Datta, whom prosecutors said provided the gun and Karla Porter's nephew, Seamus Anthony Coyle, who connected her with the shooter, are both serving life sentences for their roles in the murder.
Mowers has pleaded guilty to first-degree murder and is scheduled for sentencing July 6. Karla Porter is scheduled for trial in Carroll County Circuit Court on March 18, 2013.
