More than 400 campers and staff at Camp Modin, the oldest continuously operating Jewish summer camp in the U.S., were forced into lockdown after neighboring resident Nathan Hewett, 36, allegedly opened fire with a semi-automatic .22-caliber rifle following a confrontation with camp security.

A responding Kennebec County deputy personally observed Hewett fire roughly 20 rounds in multiple directions. Investigators later recovered shell casings whose locations suggested some shots may have been fired toward a basketball court at the rear of the camp. No one was injured. Police seized 23 firearms from Hewett’s property, many of them semi-automatic.

Court documents add a disturbing dimension: a deputy’s probable-cause affidavit says Hewett was suspected of antisemitic bias and alcohol use during the incident. No hate-crime charge has been announced. Camp officials also allege years of harassment involving gunfire, late-night fireworks, truck lights and screaming along the property line.

Hewett was initially held on $50,000 bail but has since been released. His conditions prohibit him from possessing dangerous weapons, drinking alcohol or coming within 1,000 feet of the camp. Camp Modin is now seeking a court protection order against him.
