Authorities are withholding details about last week’s crash in Buxton that killed a Bonny Eagle High School student because they don’t want to influence witness statements or a potential jury, York County’s district attorney said Monday.

Meanwhile, a Saco police accident reconstructionist is assisting with the investigation, which could take several more weeks.

Buxton police responded to the crash at 1:30 a.m. Thursday on Turkey Lane, where a car went off the road, rolled over and hit a utility pole and a tree. Three teenagers were taken to the hospital with significant injuries. A fourth teenager, Angel Greene, 16, of Standish, died in the crash.

Police have not disclosed who was driving the car, who owned the car or the identities of all the people in the car, although the district attorney confirmed that Greene was not the driver.

“At this point, the investigation is very much ongoing,” York County District Attorney Kathryn Slattery said. “We don’t want to say anything till we’re certain what occurred.”

Slattery said officers are interviewing witnesses and premature release of details about the crash could influence what people say in their interviews.

Prosecutors also are prohibited from making statements that might interfere with a defendant getting a fair trial, she said.

“I think we’re trying to be responsible,” she said. “There’s already been some misinformation released.” Slattery was referring to early media reports – based on statements from a witness – that Greene was driving the car, something she said is not true, although she would not say who was.

One of the people in the car, Zakary Pacillo, 19, of Standish, remains in fair condition at Maine Medical Center. Pacillo said Friday that the driver was 17-year-old Eddie Estey. He said Estey and Autumn Klehn, 16, both Bonny Eagle students from Standish, were in the front seat and Pacillo and Greene were in the back seat.

Police have not identified the two juvenile survivors of the crash. Slattery also would not confirm their identities. The names of the juveniles can be kept confidential because of the ongoing criminal investigation, she said. While the names of juveniles involved in car crashes are not typically withheld from the public, the names of juveniles charged with a crime generally are confidential.

Pacillo also was adamant that alcohol was not a factor in the crash.

ACCIDENT RECONSTRUCTION

Buxton police said in a news release on the day of the crash that speed was a contributing factor, but did not say whether alcohol was also a factor. However, Greene’s mother, Christa Greene, said police told her that speed and alcohol were factors in the crash.

Police routinely take blood samples from drivers in serious car crashes to determine whether drugs or alcohol were involved. The Maine Drug Enforcement Agency, the primary agency investigating drug crimes in the state, was not notified about the crash.

Buxton police are leading the investigation and are being assisted by the accident reconstructionist from the Saco police. While all full-time police officers receive some training in investigating traffic crashes during their basic law enforcement training, reconstructionists get an additional five weeks of training and must undergo annual recertification, according to John Rogers, head of the Maine Criminal Justice Academy.

Accident reconstruction uses a complex set of formulas to determine speed, direction and braking based on the location and amount of damage and the location of the car. Specially trained reconstructionists also can retrieve information about speed, braking, seat belt use and other pre-crash characteristics from an event data recorder, which is installed in most late-model cars.

Reconstructionists also work to determine who was behind the wheel when that fact is not readily apparent. That determination sometimes is based on fingerprints, DNA, or injuries that would indicate who was driving.

Saco Deputy Police Chief Raynald Demers said he expects the accident reconstruction to take about two weeks, although he said any results that are released would come through Buxton, which remains the lead agency on the investigation.

A call Monday to Buxton Police Chief Michael Grovo was not returned.
