MONTREAL - In a dramatic turn on Wednesday, Valery Fabrikant was revealed as the complainant who alleged to the Quebec College of Physicians that two Montreal cardiologists accepted payments from him.

Fabrikant, now 72, shot and killed four of his colleagues at Concordia University on 24 August 1992. He is serving a life sentence at Archambault Institution in Sainte-Anne-des-Plaines, Quebec

The former mechanical engineering professor has filed many lawsuits during his imprisonment and in 2000 was described by Quebec Superior Court as a "vexatious litigant."

In a decision released on Wednesday, the College of Physicians denied Fabrikant's special request for standing in the College's investigation against doctors Andre Pasternac and Mark Eisenberg.

In the same document, Fabrikant was clearly identified as the man who made the original complaint against the doctors for allegedly taking payments from him.

In a related lawsuit that had been winding its way through the courts for several years, Fabrikant's bid to sue the two doctors was finally thrown out by the Supreme Court of Canada in February of this year.

In that case, Fabrikant alleged that Pasternac received $5,000 and Eisenberg received $1,500 from him in exchange for access to medical services.

According to Fabrikant's claim, he borrowed money in 2010 to pay Eisenberg. This payment was made to assure that when and if needed, Eisenberg would perform angioplasty on the patient.

Fabrikant also alleged that in October 2009, he borrowed money and paid Pasternac $5,000 by cheque. This payment was in addition to his regular fees that were paid by correctional service.

The payment was made on condition that Pasternac would provide necessary cardiac care for Fabrikant when and if needed.

According to a court decision, both doctors returned the money to Fabrikant.

Despite returning the money, the court ruled that, "the doctors admit having accepted substantial amounts of money from Fabrikant in circumstances that have not been clearly explained."

The court rejected Fabrikant's lawsuit and suggested it was up to the College to rule on whether the doctors violated its code of ethics.

With hearings set for a later date, the College will investigate the allegations, but Fabrikant will not be given a special status at those hearings.

According to the College, Fabrikant was the only complainant in this case.
