One of two Ottawa men shot dead in a mall tanning salon last month allegedly owed a million dollars to a man on trial for assaulting two of his friends, an Ottawa court heard Thursday.

Kevin Foisy is a friend of Graham Thomas, the Ottawa man who, along with Jason Chapman, was shot dead last Wednesday at Caribbean Exposure, a tanning salon in the Gloucester Centre shopping mall. Police said the shooting of Thomas and Chapman was not random.

Foisy, who owns the Caribbean Exposure name and runs a salon out of Merivale Mall, was testifying Thursday at the trial of Jeffrey Latimer, who is charged with assaulting Foisy.

Foisy told the court Latimer charged him in the Merivale Mall parking lot on May 31, 2010 and punched him.

He added the alleged assault came 10 months after Latimer called him and accused Foisy about lying about his share of a supplement business he ran with Thomas.

Foisy said Latimer told him that Thomas owed him money and warned Foisy that Thomas would "rip you off too."

Foisy said he later received a phone call warning him that if he did not drop the police complaint, his life would be in jeopardy. Foisy would not say who made that phone call.

Latimer has pleaded not guilty to the assault. The trial continues.

Latimer was also charged with assaulting another of Thomas's friends — Jacques Lavoie. Proceedings in that trial ended Wednesday with the judge expected to release a judgment later this month.
