BANGOR — A Penobscot County Superior Court jury found Rory Holland guilty on two counts of murder this afternoon.

Holland, 56, of Biddeford, was accused of shooting Gage Greene, 19, and his brother, Derek Greene, 21, on the sidewalk outside their home on South Street in Biddeford.

The verdict was reached after closing arguments this morning in a trial that was moved to Bangor at the request of Holland’s attorneys.

The jury deliberated for 3 hours and 15 minutes, after Assistant Attorney General Lisa Marchese and defense counsel Clifford Strike made their closing arguments.

Holland seemed calm and showed no emotion as the verdicts were read.

Another of his lawyers, Amanda Doherty, said she was surprised by the speed with which the jury reached its decision. She said an appeal was likely.

Outside the courtroom after the verdict, members of the Greene brothers’ family said they felt vindicated.

“My boys died as heroes, because now everyone is now safe from this man,” said the Greenes’ mother, Tammy Cole of Biddeford.

The prosecutor, Assistant Attorney General Lisa Marchese, said sentencing would take place in York County Superior Court, at a date not yet chosen.

“I am most gratified because Rory Holland is a dangerous presence in Biddeford and he needed to be off the streets,” she said.

Holland faces a sentence of 25 years to life on each guilty count, and Marchese said she would seek a substantial sentence given Holland’s criminal history and the fact that there were two victims.

Holland was convicted of attempting to murder his 16-month-old daughter in Kansas in the 1970s.
