cannibalist coven that would later lure Dexter and Debra into a trap, later saving them from the cannibals. Joe Driscoll Joseph "Joe" Driscoll was the biological father of Dexter. His exact relationship with Laura Moser is not made clear, nor is it specified whether he fathered Brian Moser as well. Joe claimed he got his spider web tattoo on his right elbow while serving in the Vietnam War, but Dexter notes it is actually a prison tattoo. When Laura was exposed and murdered for being involved with the police in their attempts to bring a drug cartel to justice, Joe went underground and resettled in Dade City, Florida working as an insurance adjuster.

Rudy and Dexter stole Joe's ashes and scattered them at Joe's local bowling alley. Joe and Dexter, when compared, are shown to have great physical resemblance, and Dexter also inherited his father's bowling
