An 8-year-old boy from Eddington died unexpectedly Wednesday, and the Penobscot County Sheriff’s Office is investigating the death, the local school district said.

Further information about the death of Isaiah Perry was unavailable Friday, and the sheriff’s office declined to release any further details.

“With a heavy heart, I am informing you of the very untimely and tragic death of one of our students,” wrote Regional School Unit 63 Superintendent Susan Smith in a message posted Wednesday to the district’s website. “Isaiah Perry was in Mrs. Palmer’s third grade class at the Holden School. We knew Isaiah as a wonderful, friendly child.”

Smith, in a brief telephone interview Friday, said Isaiah came to the district midway through his second-grade year.

It was unknown how or where the boy died.

“We don’t know what the cause of death was. I spoke with the sheriff’s office earlier this morning, and they’re still investigating,” Smith said.

Children, parents, staff and community members gathered at Holden Elementary School on Friday to remember Isaiah and “receive support from one another and area counselors,” Smith said in an email Friday night. RSU 63 serves Holden, Eddington and Clifton.

“Isaiah’s death is a sad and difficult occasion. … It was unexpected and tragic,” she wrote. “Hold your loved ones just a bit closer and give them a hug.”

Holden will have counselors at school on Monday, too. Smith said parents, staff members, and others who volunteer or work with children are also invited to come to the school at 7 p.m. Wednesday to learn more about how to help children deal with grief and loss.

Don Spencer, the principal of Holden Elementary School, said Isaiah was an outgoing boy who participated in Saturday morning soccer and pee-wee basketball. He was also a Cub Scout.

“The staff pulled together today,” Spencer said Friday. “He was a well-liked kid, so we had a lot of kids here today.”

School on Monday will be held as scheduled.

“Regular structure and a predictable schedule are helpful to children. School day activities and routines will take place; however, school staff will be flexible as needed,” Smith’s post said.
