Jill Mayer, now a deputy director in the state Division of Criminal Justice, will replace Camden County Prosecutor Mary Eva Colalillo, who retires on Sept. 30 after more than five years in the position, according to a release.

The release from the Attorney General’s Office states that “Mayer has prosecuted cases involving violent gang members, drug dealers, financial crimes, racketeering, and casino crimes.” Among her roles was supervising the 2014 dismantling of a violent narcotics distribution enterprise that was dealing millions of dollars a year in heroin and cocaine in Camden through its ties with Mexican drug cartels, the office said.
