A Sicklerville man who still faces a South Jersey murder charge pleaded guilty in federal court in Camden on Wednesday to conspiring to purchase 13 kilograms of cocaine for distribution throughout New Jersey, U.S. Attorney Paul J. Fishman announced.

Jamal Herrin, 40, pleaded guilty before U.S. District Judge Joseph H. Rodriguez to one count of knowingly and intentionally conspiring to distribute and possess with intent to distribute more than five kilograms of cocaine

Herrin was free on $1 million bail in connection with a New Year's Eve 2012 homicide inside Old School Nostalgia Barber Shop, in Winslow Township's Sicklerville section, when he became the focus of a Drug Enforcement Administration probe launched in April 2012.

Herrin admitted he negotiated the purchase of 13 kilograms of cocaine and amassed more than $325,000 to purchase the cocaine, Fishman said.

Herrin faces a mandatory minimum prison sentence of 10 years and a potential life sentence on the drug charge.

The U.S. Attorney's Office only identified Herrin as a Camden County resident in a press release it issued regarding Wednesday's guilty plea.

The Camden County Prosecutor's Office identified Herrin as a Sicklerville resident when he was arrested in early January 2012 and charged with murder in the Dec. 31, 2011, shooting death of Terrance Barnum, 40, of Williamstown, inside the Sicklerville barbershop.

Herrin previously resided in Clementon, according to the U.S. Attorney's Office.

In addition to at least 10 years in federal prison, Herrin faces up to a $10 million fine on the drug conspiracy charge. Sentencing is scheduled for April 15.
