Vancouver Sunny Park knew the grisly fate that awaited her and her family. She didn't know when or how it would occur. But she knew who her killer would be - and she knew police could do nothing about it. She sat in the police interrogation room, already a broken woman, as she told officers that her husband was going to kill her. A white bandage on her nose was clearly visible, as was the bruise on her face. Her arm was in a sling. Park had just survived the first attempt on her life, in which her husband deliberately rammed their vehicle into a pole. The police interview was conducted in June last year. Park's words were deadly calm as she told the officer what her husband said to her just before the car struck the pole. 'I'll kill everybody and I'll kill myself,' Park recounted. 'It gets worse every time.' Five weeks after the interview, Park's estranged husband, Peter Lee, followed through on his threats. He broke into the family home in the upscale community of Oak Bay near Victoria on Vancouver Island. A frantic 911 call brought police to the scene - but not before Lee, a well-known restaurateur in the city, had stabbed to death his wife, her elderly parents, and his six-year-old son. He then fatally stabbed himself in the heart. Last week a coroner's inquest into the killings raised serious concerns about the system that should have protected Park. Park told the police officer who interviewed her that her husband knew all the tricks to get around the law as he terrorised her after the car-crash incident. Even though he was on bail and ordered to stay away from the family home and the restaurant the couple owned, Lee dodged the requirements. His bail supervisor didn't even know where he was living. The day he was scheduled to appear in court again was the day he murdered his family. Questions remain over the culpability of every official in the police and court system who played brief roles in the tragic case. The Oak Bay killings were troubling enough. But they became even more so when a frighteningly similar scenario had unfolded in Merritt, about three hours' drive east of Vancouver. There, the bodies of three children under the age of 10 were found murdered in their home last month. It emerged that the children's father, Dwayne Schoenborn, now accused of the killings, had been taken into custody just three days before the murders for uttering threats at the children's school. But Schoenborn was freed on bail by a justice of the peace, who said he was giving him 'a bit of a break'. Schoenborn is now back in jail - facing three counts of first-degree murder. Police conduct has come into question in both the Oak Bay and Merritt cases. In the Merritt murders, it took police 20 hours after the killings to inform residents that Schoenborn, their prime suspect, was on the loose. Many residents assumed he had committed suicide inside the home. Schoenborn was to remain on the loose for 10 days before a local hunter tracked him down and called police. In the Oak Bay killings, police responded within minutes to the 911 call. But because the house was located in an exclusive enclave with its own police force, there was initial confusion about who was in charge. Officers did not enter the home until hours later. The stinging legacy in both cases, and the aspect most troubling, is how easily the two fathers slipped through the fingers of the system. Tomorrow: New York
