A memorial service for a Seymour native whose small plane went down Oct. 31 near Cape Cod off the coast of Massachusetts has been set.

It will be at 7 p.m. today at Voss and Sons Funeral Service in Seymour.

Roger Mills, 67, of Woburn, Massachusetts, is believed to have been the only person on board the Piper PA-28 at the time it went down, according to The Associated Press. Mills had been flying from Indiana to Massachusetts at the time.

The plane took off from Reading Regional Airport in Pennsylvania on Oct. 31 and was scheduled to land at Chatham Municipal Airport in Chatham, Massachusetts, by about 8 p.m. A friend waiting at the airport reported Mills had not arrived as scheduled.

Divers with the Massachusetts State Police later located the plane, but Mills was not found, The AP reported.

The reason the plane went down also is unknown. It may have been due to a catastrophic plane failure or an unknown health issue.

The plane was found Thursday about 3.5 miles east of Orleans in 70 to 80 feet of water, Chatham Harbormaster Stuart Smith told the Cape Cod Times.

Mills was born in Seymour to Robert and Anne Breitfield Mills and was a 1973 graduate of Seymour High School.

A National Transportation Safety Board spokesperson reported the agency has opened an investigation into the crash.
