In dramatic testimony Tuesday, Rocky Rambo Wei Nam Kam described killing Dianna Mah-Jones and Richard Jones in their Vancouver home.

The trial of a B.C. man accused of murdering a couple in their West Side Vancouver home two years ago came to a sudden halt on Wednesday.

Crown presented a mountain of surveillance videos collected from businesses, transit buses and homes, which prosecutors say show Kam in the area several times before and after the killings.

A forensic expert told a Vancouver double murder trial Monday that the accused's DNA was found on a murder weapon and under one of the victims' fingernails.
