ELLSWORTH – A Lamoine man accused of driving a truck involved last weekend in a fatal accident in Dedham appeared in court Tuesday on charges of vehicular manslaughter and aggravated assault.

Bail for Sean George, 27, was set by Ellsworth District Court Judge Bernard Staples at $25,000 single surety or $2,500 cash.

Staples set a date of June 18 for a probable cause hearing for George in District Court, but the defendant likely will be indicted and have his case transferred to Hancock County Superior Court before then, according to officials involved in the case.

George allegedly was driving a 1997 Ford truck south in the northbound lane of Route 1A around 8 p.m. Friday when the truck collided head-on with a 1996 Dodge car, according to police.

Bethany Edmondson, 19, of Mount Desert, was a passenger in the Dodge and died at the scene after suffering a massive head injury and internal injuries in the accident, police have said.

George told police who responded to the accident that he had consumed beer and a mixed drink earlier that evening, according to an affidavit filed in Ellsworth District Court. Police gave George field sobriety tests at the scene and, after concluding he was impaired, took him to Maine Coast Memorial Hospital in Ellsworth to obtain a blood sample, the affidavit indicated.

George, wearing green pants and a black and white striped shirt issued by Hancock County Jail, did not address the court Tuesday during his brief appearance.

George’s defense attorney, Robert Granger of Ellsworth, told Staples that George is a recent graduate of University of Maine and, before the accident, had been working as a residential child care worker for KidsPeace, a residential youth treatment center in Ellsworth. He argued for lenient bail because of George’s connection to the area.

“He has significant ties to Lamoine,” Granger said.

George has lived in Lamoine for five years and owns property there, according to the defense attorney. He also said George has no prior criminal record.

Hancock County Deputy District Attorney Carletta Bassano said Tuesday after the hearing that George has not been charged with operating a motor vehicle while under the influence of intoxicants because the results of his blood test are not complete.

“That usually takes a few days,” the prosecutor said. The results of the test will determine whether George also is charged with aggravated OUI in connection with the accident, she said.

Injured in the collision were Steven Roberson, 25, of Orrington, and Joel Fougere, 24, of Alfred.

Roberson, the driver of the Dodge, suffered a broken pelvis, while Fougere, a passenger in George’s truck, had a serious head injury, according to police. Air bags deployed in both vehicles, but no one in either vehicle was wearing a seat belt, police have said.

A spokeswoman at Eastern Maine Medical Center in Bangor said Tuesday that Roberson is in fair condition at the hospital. She said Fougere is at the hospital but, at his family’s request, his condition is not being released publicly.
