DOVER — A man has died after being found with a gunshot wound Tuesday night outside Castaways restaurant, according to authorities.

George Maglaras, commissioner of Strafford County and owner of the restaurant property, said the incident was recorded on surveillance cameras and he voluntarily gave the recordings to investigators.

Dover police responded at about 10 p.m. to 31 Cocheco St., which is the restaurant's address. Upon arrival, police discovered the man with an apparent gunshot wound. His identity is being withheld until family can be notified, police said.

Castaways was closed on Wednesday "out of respect for what happened," said Peter Kilty, who owns Castaways, renting the property from Maglaras. He said he does not know when or if the restaurant will reopen.

Kilty said he was not at the restaurant on Tuesday night when the incident allegedly took place. Kilty, who has owned the restaurant since 2005, said Tuesday was a slow night. He said he was upset to hear that what seemed to be a minor disagreement between two people escalated into a deadly incident.

"This is not the kind of place that thrives on drama," Kilty said, adding that most of his clientele in from an older demographic. "This is not a place people come to cause problems. Our hearts go out to both families, especially at Christmas time. It's an incredibly sad situation."

Kilty said he did not know the alleged victim but was told he had been a previous patron at Castaways.

Senior Assistant Attorney General Peter Hinckley said the victim's age is also being withheld pending an autopsy, which was scheduled for Wednesday by the New Hampshire chief medical examiner’s office. Hinckley said he expects that information to be available Thursday. Hinckley said there were no arrests. Maglaras said he believes one person was taken into custody Tuesday night.

Police said they believe they have identified all the parties involved and there is no evidence to suggest there is a threat to the general public. Additional information will be released as it becomes available, they said.

Anyone who has information about the incident is asked to contact Sgt. Mark Nadeau at the Dover Police Department at (603) 742-4646.
