A suspended Mountie accused of killing an Ottawa police officer knew the difference between right and wrong and can be held criminally responsible for his actions, according to a psychiatric assessment.

Kevin Gregson, who is facing first-degree murder charges in the death of Const. Eric Czapnik, was ordered to undergo an evaluation of his mental state in April. Gregson has already been found fit to stand trial.

His lawyer says although the psychiatric evaluation suggests Gregson was aware of his actions, the defence will consider asking for a second opinion.

Czapnik's widow sat in the front row of the courtroom on Friday to face her husband's accused killer for the first time.

Anna Korutowska stared intently at the man charged with killing her husband, and briefly wiped tears from her face. She did not speak to reporters following Gregson's court appearance.

Nine new charges

Gregson is also facing nine new charges in connection with incidents that occurred prior to his arrest.

He is charged with four counts of sexual assault causing bodily harm, four counts of sexual interference, as well as one count of possessing child pornography.

The sexual assault charges involve a minor, and the circumstances of those charges are covered by a publication ban in an effort to protect the alleged victim.

"He will put a vigorous defence forward. He denies the charges," said defence lawyer Geraldine Castle-Trudel.

Gregson has also been charged with using an imitation firearm, as well as stealing a vehicle that was found parked at the civic campus of the Ottawa Hospital, where Czapnik was stabbed to death in late December 2009.

Nearby paramedics tried to revive the officer, but were unable to save him. He was pronounced dead 90 minutes before the end of his shift.

Gregson will appear in court on the sexual assault charges on June 21. A preliminary hearing on the first-degree murder charges is scheduled for Oct. 2.

Gregson was suspended with pay from the RCMP in 2006. His pay was later revoked in April 2007.
