Marlborough man found guilty in 2009 shooting death of teen at Callahan State Park in Framingham

A 20-year-old Marlborough man has been found guilty in the 2009 shooting death of a 17-year-old at Callahan State Park in Framingham in 2009, Middlesex District Attorney Gerry Leone said Wednesday.

Leone said that the defendant, Marquise Brown, was found guilty by a Middlesex jury on a charge of first degree murder. The Middlesex Superior Court trial lasted seven days.

Brown's sentencing is set for September 26.

“The defendant senselessly shot and killed the victim in broad daylight in a public state park,” Leone said in a statment. “This case is another tragic example of a young person resorting to guns and violence to resolve perceived conflict. We are pleased that the defendant will be held accountable for his actions and that we are able to provide some measure of justice for Tyriffe and his family.”

Brown was convicted of killing Tyriffe Lewis, 17, who was found with gunshot wounds on June 20, 2009 by Framingham police and emergency personnel who were called to Callahan State Park.

According to Leone's office, police that a day earlier the two men and others had been at a party in Marlborough. There was an argument over drugs and money, and Lewis gave Brown a black eye in front of friends and family.

"Immediately after the fight, Brown told others he was going to kill the victim and anyone who snitched on him,'' Leone's office said.

According to Leone's office, Brown and another defendant, Yessling Gonzalez, 22, who is also facing murder charges, met with the victim Marlborough and drove to the park. The case against Gonzalez is pending.

"Gonzalez drove to the park and upon their arrival the three men walked about 100 yards into the woods. Brown produced a semi-automatic handgun and shot the victim twice. The defendants fled the park in Gonzalez’s vehicle,'' Leone's office said in a statement.
