A Toronto man who will be sentenced in the United States next month for procuring weapons for the LTTE described in court documents how that same group murdered his father.

Thiruthanikan Thanigasalam, 43, said in a sentencing memorandum in U.S. District Court that he fled to Canada after the Tamil Tigers took away his father and shot him eight times for refusing to give them money.

Mr. Thanigasalam did not explain why, while living in Canada years later, he would take part in an illicit conspiracy to buy black market weapons for the LTTE that had killed his father.

U.S. officials have depicted Mr. Thanigasalam as the technical expert of the group, and allege he had sought missiles that could shoot down the Kfir fighter jets used by the Sri Lankan military, reported National Post.

Asked why Mr. Thanigasalam would support the LTTE after they killed his father, his lawyer Lee Ginsberg said, "I can't explain it. I'm not sure my client can explain it".

If you want my view for what it's worth, it wouldn't surprise me if there are many Tamils who were upset with the way the LTTE was operating in Sri Lanka and had family members displaced because of them, he said.
