Instead of making their sentencing submissions, Mohamed Karim's lawyers are pouring through hours of surveillance videos.

Mohamed Karim was convicted in the death of Jack Beauchamp, 49, the head of a mortgage lending company, who was shot six times and found dead in his downtown office in January 2006.

Karim said the videos from both the remand and court centres will prove he was abused by sheriffs verbally, physically and sexually.

Much of the alleged abuses, he says, are racially and religiously motivated.

"When someone calls me a rag head, camel jockey, Taliban, Osama bin Laden — as I was called thousands of times by officers — I don't let go," Karim said."What I do is complain. You use the complaints process."

He says he believes the harassment worsened because sheriffs were angry he'd complained.

"[The sheriff] picked up my Qur’an and just ripped it apart while he was looking at me and just threw it on the ground, started stomping on it and tears, tears in my eyes and I couldn't do nothing," Karim said, adding all of this happened while he was handcuffed with another officer laughing while watching on.

Re-trial granted

Initially convicted of first-degree murder, Karim and his co-accused, Robert Deer were granted a re-trial. In September, Justice Beth Hughes found Karim guilty of second-degree murder and Deer guilty of manslaughter.

On one of the first days of the re-trial, Justice Hughes ordered sheriffs to give back prayer sheets they had taken from Karim.

His lawyer, Shamsher Kothari, says he won't comment on specific allegations until he's had enough time to go through the videos.

"There was the issue at the beginning of the trial where his prayer papers were taken away, so that's one of the components, but until we review the videos we can't ascertain entirely what the allegations are," he said.

Karim says although much of the abuse was centered around his religion, on one occasion it was sexual and on at least one other, physical.

"I was assaulted on camera while I was handcuffed, taken down, punched and kicked, threatened to be killed," he said. "I was taken down and just beat up, beat up, beat up, so bad."

Kothari says he hopes the public can look past his client's murder conviction.

"Individuals who are in custody ought to be treated a certain way regardless of whatever their convictions are or allegations against them so when individuals at the remand centre or inmates in other institutions are alleging certain mistreatment, it becomes an issue whether or not it will affect sentencing," said Kothari.

A spokesperson from the Solicitor General's office wouldn’t comment on the specific case.

"Anytime we become aware that a criminal activity may have occurred, police are called. As well, inmates may call police themselves if they choose," wrote Michelle Davio, of Alberta Justice and the Solicitor General's office, in an email.

Kothari said if abuses are found on the videos, it could affect defence sentencing submissions. A new date will be set once the lawyers have a chance to review all videos. Robert Deer's lawyers will proceed with his sentencing Tuesday morning.
