BANGOR, Maine — Jury selection for the trial of a York County man accused in the hit-and-run death of a University of Maine student 18 months ago is scheduled to resume about 1 p.m. Monday after a lunch break.

Nearly 150 potential jurors who live in Penobscot County showed up Monday morning at Penobscot Judicial Center for the jury selection process.

If the jury selection can be completed by mid-afternoon, jurors could hear opening arguments in the case against Garrett Cheney, 23, of North Berwick on Monday. It’s more likely that the trial will get under way Tuesday morning, according to Penobscot County District Attorney R. Christopher Almy.

The trial is scheduled to last through next week with testimony expected from more than two dozen witnesses for both sides.

Cheney is charged with manslaughter, aggravated criminal operating under the influence of intoxicants, leaving the scene of an accident that resulted in serious bodily injury and criminal operating under the influence of intoxicants.

Cheney allegedly struck and killed University of Maine junior Jordyn Bakley, 20, of Camden about 3 a.m. Jan. 30, 2010, in front of 15 Middle St. in Orono near her apartment. He was driving on the wrong side of the street when he struck Bakley, who was killed instantly, according to court documents.

He was in Orono on Jan. 29 visiting a cousin to celebrate the cousin’s 21st birthday, according to an Orono police affidavit filed at the time of his arrest on April 16, 2010.

After allegedly hitting Bakley, Cheney headed south on Interstate 95. His 2003 Chevy Silverado went off the highway about 3:30 a.m. in Etna, according to the affidavit. The damaged pickup was towed to the storage lot of a Newport towing firm.

Cheney was not injured but was charged with drunken driving. His blood alcohol level was 0.15 percent, nearly twice the legal limit, two hours after his truck left I-95, according to the affidavit.

Bakley was a 2007 graduate of Camden Hills Regional High School, where she was a talented swimmer and active in the Diversity Coalition and Water Monitoring Program, according to her obituary. She was an advocate for a number of humanitarian causes and spent one summer volunteering for a program that worked to keep inner-city kids off the streets and another as part of a Habitat for Humanity group that built a home in Mississippi.

If convicted of manslaughter, the most serious crime with which he is charged, Cheney, who has no criminal history, faces up to 30 years in prison and a $50,000 fine.
