Mercer County Sheriff’s officers tracking a fugitive gang member wanted in the city on weapons offenses followed his trail to Willingboro, Burlington County, where they arrested their man and three other people, while also happening upon a loaded weapon, drugs and funny money.

The hunt began April 6, when sheriff’s officers spotted a suspect on Kirkbride Avenue in Trenton with what appeared to be a gun.

When officers went to investigate, the suspect, later identified as James Hughes, ran in through the front of a home on Kirkbride, then ran out the back door, officials said.

The suspect managed to get away, officials said, but during the chase the officers reported seeing him discard a gun. The loaded .40-caliber Taurus handgun was recovered with a defaced serial number.

Officials said detectives managed to identify the 26-year-old Hughes, and warrants for weapons offenses and other charges were issued. Officials called him a “documented member of the Bloods Street gang.”

As they searched for Hughes, officials said, detectives received information that the fugitive may be hiding out at a girlfriend’s house on Granby Lane in Willingboro. Officials identified the girlfriend as 29-year-old Monet Muse.

Officers went to the Granby Lane home Thursday, but Hughes wasn’t there. They did find Muse, another woman named Kyla Muse, 28, who also lived at the home, and her boyfriend, 31-year-old Sultan Freeman, of Camden.

During their investigation, officials said, detectives recovered 57 grams of marijuana, $980 worth of counterfeit $20 bills, and what turned out to be a stolen .357 Magnum revolver, fully loaded with hollow-point bullets. A check of the gun showed it was reported stolen from Burlington in 2009.

Officials said Monet Muse was charged only with possession of marijuana, and she was released on her own recognizance.

Freeman and Kyla Muse are facing multiple charges in connection with gun possession and the counterfeit cash. Freeman was additionally charged as a previously convicted felon in possession of a weapon.
