BANGOR — The prosecution rested its case Monday in the murder trial of Rory Holland, and as the defense began calling its witnesses, it remained unclear whether Holland would take the stand.

Holland, 56, is charged with killing two brothers, 21-year-old Derek Greene and 19-year-old Gage Greene, in a confrontation outside Holland’s home in Biddeford on June 30, 2009.

He contends that he shot the men in self-defense. He has been incarcerated since his arrest, hours after the shootings.

Testimony is expected to continue through today, and the case may go to the jury Wednesday.

On Monday, Danny Rydle of Old Orchard Beach testified for the defense that on May 12, 2009, Derek Greene told him and another friend, Elijah Copeland, that Holland had groped him at Holland’s house.

In response, Rydle testified, he and Copeland tied bandanas over the lower halves of their faces and accompanied Derek Greene back to Holland’s house. Copeland also testified Monday, but he and Rydle gave conflicting accounts of exactly what happened next.

Both men told jurors that Derek Greene punched Holland a couple of times.

Rydle said Copeland pushed Holland. Copeland said he did not touch Holland, but pulled Derek Greene off him and carried Greene home on his shoulders.

Later, Holland was at nearby Williams Court, where Gage Greene lived and where the group of young men often gathered.

Biddeford police Officer Tanya Caywood said she was approached by Holland, who reported that he had been assaulted by the men and wanted them arrested.

Caywood testified that while she was talking to Holland, Copeland and Derek Greene were yelling that he was a pedophile, and Greene punched Holland in the presence of officers.

Under questioning by Holland’s attorney, Clifford Strike, Caywood said the young men outside Gage Greene’s apartment were agitated, drunk and aggressive.

Copeland told jurors that he and Derek Greene were “angry, stupid and drunk” at the time. He admitted to calling Holland a pedophile and using a racial slur during the confrontation. Holland is African-American.

Derek Greene and Copeland were arrested that night. Both were given bail conditions prohibiting them from being around Holland.

For most of the trial, the defense has suggested through its line of questioning that Holland had good reason to be afraid of the Greene brothers and their friends. Several of those friends witnessed the shooting at 1 a.m. on June 30, 2009, and the defense has tried to paint a picture for the jury of Holland being nearly surrounded when he fired the gun.

Testimony last week indicated that Gage and Derek Greene and Brandon Bernadino were walking along South Street on their way home when they saw Holland standing on the sidewalk outside his house.

Gage Greene ran across the street, confronted Holland and pushed him. Witnesses said Holland immediately pulled a gun out of his waistband and shot Greene in the chest.

When Derek Greene ran toward them, Holland shot him three times.

Gage Greene died at the scene. Derek Greene died en route to the hospital.

Testimony from eyewitnesses has been conflicting, as each one has admitted to being drunk and smoking marijuana on the night of the shootings.

On Monday, Copeland’s testimony often conflicted with that of his girlfriend, Doreen Smith-Mason, who testified just before him.

Smith-Mason admitted under tough questioning by the defense that her testimony that Copeland was in Gage Greene’s apartment at the time of the shooting was different from what she told police immediately after the shooting, when she said he was outside.

Where Copeland was when the shootings occurred is important to the defense as it makes a case that Copeland was with the Greene brothers in front of Holland’s home, providing more reason for Holland to be fearful.

Smith-Mason testified Monday that she was in Gage Greene’s apartment just before the shootings and heard yelling outside.

She said she was sitting on a couch in a bay window, looked outside and saw Holland shoot Gage Greene.

Defense attorneys questioned her credibility, showing photos of Holland’s house in proximity to Gage Greene’s apartment and expressing doubt that she could have seen the shooting from Greene’s window.

When Copeland testified, he said that he – not Smith-Mason – was sitting on the couch in the apartment when the shooting occurred, and that Smith-Mason was across the room and could not have seen the shootings.

Copeland is expected to be back on the stand this morning in the Penobscot Judicial Center, and the defense plans to call a neighbor and Holland’s former girlfriend.

Holland could be sentenced to 25 years to life in prison if he is convicted of the killings.

The trial is being presided over by Justice Ronald Cole and being heard by a jury of eight men and eight women, including four alternates.
