A man accused of a violent home invasion in which a drug dealer was robbed at gunpoint took the stand in his own defence Friday.

Derry Bird, 22, denied all of the charges against him. He told court he was at home the night of the May 2012 home invasion in Emyvale, P.E.I., smoking marijuana in his parent's basement. 

His parents backed up that statement in their testimony. The father said he had berated his son that night for smoking marijuana in the house.

The court also heard Derry Bird was on Facebook around the time of the attack.

Earlier in the week other witnesses testified linking Bird to the home invasion.

Micah MacDougall, 21, took the stand for the prosecution on Thursday. MacDougall was recently released from jail on an unrelated drug trafficking incident.

He told the court he was at a meeting with Bird when plans for the home invasion were discussed.

Two masked men forced their way into the home on May 28, 2012 said police, and then tied up, assaulted and robbed the man living there. Police said both intruders were in possession of firearms.

Bird and 23-year-old Chase Roper were charged with the attack. 

Three others were charged with being a party to the offence of the robbery.

Judge to rule Dec. 17

MacDougall told court the drug trade on P.E.I. damages the people involved and their families.

"It's not worth it. It might seem worth it at the time, but when it's all said and done it's not worth it. It affects families. It affects you. It affects the people you sell drugs to and it sucks to go down that road,” he said.

Crown prosecutor Cindy Wedge asked for an extension of the trial so police can further investigate the alibi presented by Bird and his parents.

Justice Gordon Campbell must now decide whether to grant the request. He will hear the arguments Dec. 17.

The firearms used in the home invasion, a sawed off shot gun and a hand gun have not been recovered. 

Three people, including Bird's former girlfriend, have pleaded guilty to their roles in the crime. Two testified Derry Bird was involved. The third originally told police Bird was involved, but changed his story on the stand this week.
