The Atlantic County Sheriff’s Office is warning of a scam in which an individual claiming to work for the agency is calling residents to tell them they have warrants for their arrest. The person identifies themselves as Captain Hendrickson or Officer Kevin Henry and tells the victim they missed jury duty or another court function and are required to come to the courthouse for a signature verification to determine that they didn’t sign a certified letter or subpoena, the Sheriff’s Office said in a Facebook post.
