NEW WESTMINSTER -- A Surrey cab driver stabbed his wife to death after she threatened to turn their son against him, he testified Friday.

Jatinder Wariach, 25, testified that just before the killing, he and Navreet had been arguing, with his wife demanding that he pay all costs for her parents to immigrate to Canada. He had already signed over to her one-third of his $220,000 share in his cab, jurors heard.

He'd refused and during an argument in their Surrey basement suite she told him she was leaving and would take their son, Bharmveer, to India, where her parents still lived, he said.

"You know my parents," Waraich claims Navreet threatened. "They are going to train him so much that he will spit on you and your parents," he testified.

"When she said that, I lost my control and I felt very much insulted," he said.
