N. Pringer was a citizen of Sandford.
When Nicholas Angel first arrives in the town and goes to the pub, he sees that there are many underage drinkers, so he kicks them all out. Pringer comes across as a very cocky individual, and disrespects Angel, unlike his friends, who are scared of him. Afterwords, when Nicholas is taking a drunk back to the station, he comes across Pringer urinating on a fence and he is arrested.
Later, when the Neighbourhood Watch Alliance is revealed to be a murderous cult and attempts to kill Nicholas, Pringer's corpse is found underneath Callahoun Park. He was killed for his drunken indescretion.
