The Quincy man charged with bringing a gun to Roxbury court for an associate’s arraignment on his own gun charges has been indicted and will appear Friday in Suffolk Superior Court, Suffolk County District Attorney Daniel F. Conley said today.

The Suffolk County Grand Jury yesterday returned indictments charging JAQUAN BENNETT (D.O.B. 6/6/91) with unlawful possession of a firearm as a second or subsequent offense, unlawful possession of ammunition, and unlawfully carrying a loaded firearm.

Bennett was previously convicted of gun charges in the Suffolk County Gun Court in 2009. He served 18 months in the house of correction and was on probation for that offense at the time of his arrest Thursday. As a second-time offender, Bennett faces at least five and up to seven years in state prison if convicted.

“The evidence suggests that this defendant brought a gun to court in apparent support of another gun defendant,” Conley said. “That’s absolutely chilling, not just for its brazen disregard for the law but for the threat it poses to everyone in that building. These indictments should send an unmistakable message that this behavior won’t be tolerated, period.”

Bennett was arraigned April 29 in Roxbury court – the same courthouse to whose parking lot he allegedly brought a handgun in a gypsy cab one day earlier. He was held on $25,000 cash bail.

During those proceedings, Assistant District Attorney Matthew Feeney of Conley’s Gang Unit told the court that Bennett was present at Roxbury court the previous afternoon for the arraignment of GIROLD GRAND-PIERRE, charged in connection with shots fired near Tremont Street and Melnea Cass Boulevard last week. After a motor vehicle pursuit, Boston Police watched Grand-Pierre allegedly toss two loaded handguns into a Dumpster. Grand-Pierre is similarly charged as a second or subsequent gun offender and is held on $20,000 cash bail.

While Bennett was being arraigned, a separate Gang Unit prosecutor began introducing evidence in the Suffolk County Grand Jury to ensure as rapid a turnaround as possible. Members of the Boston Police Youth Violence Strike Force assisted them by serving grand jury subpoenas on civilian witnesses, driving those witnesses to court, and transporting physical evidence to ensure that all the procedural requirements were met.

Both Bennett and Grand-Pierre are impact players associated with the area of Mission Hill, Ruggles Street, and Annunciation Road, prosecutors say.

Roxbury court officers notified Boston Police of a large contingent of young men believed to be Grand-Pierre’s associates. As they left the courthouse and officers arrived, several members of that group began to walk quickly in the other direction.

Bennett quickened his pace at the sight of police and walked to a white minivan in the parking lot. The minivan was blocked from leaving by heavy traffic, however. Officers then watched as Bennett opened the rear door and exit, only to stop, reach back inside, and then close the door behind him.

The officers approached Bennett and the minivan. One officer engaged the defendant in conversation while another spoke with the driver. The latter officer noticed what appeared to be a firearm in a pocket mounted on the back of the front passenger’s seat – right where the officers had seen him reaching. He opened the door and found the item to be an FEG 9mm semiautomatic handgun loaded with one round in the chamber and seven in the magazine.

It became apparent in subsequent interviews that the minivan driver was a gypsy cab driver and not an associate of Bennett. The driver told Boston Police that he had been asked to drive Bennett and another man to Roxbury court, then told to wait while they went into the courthouse.

Bennett is represented by attorney Jack Miller. He will be arraigned Friday morning in the Magistrate’s Session of Suffolk Superior Court, located on the seventh floor of the courthouse.
