Gazette - Snaring Pickton
by Caroline Ross
On February 5, 2002, rookie Cst Nathan Wells of the Port Coquitlam RCMP Street Enforcement Unit executed his second-ever search warrant at a pig farm outside Vancouver, B.C. Two members of the Vancouver Missing Women Task Force (MWTF) stood by off-site. Wells and his unit colleagues were looking for a firearm. The MWTF was looking for a needle in a haystack. The task force — a joint RCMP–Vancouver Police initiative — was investigating the disappearances of some 50 women from Vancouver’s Downtown Eastside. The farm was on the radar because it belonged to one of the task force’s 60 persons of interest. The task force was hoping for a break. It got one.
In a trailer owned by Robert “Willie” Pickton, the search team found identification and a prescription inhaler belonging to two women who had recently gone missing from the Downtown Eastside. It was the first crack in the case against Pickton, who would later become Canada’s worst alleged serial killer, charged with the first-degree murders of 27 women whose remains or DNA were found on the farm.*
How did the MWTF arrive at this critical break? It wasn’t luck, says Don Adam, the now-retired RCMP inspector who headed the MWTF until November 2004. It was sound methodology and solid teamwork that cracked the case — that and a willingness to assess the costs and benefits of every decision upon which the investigation was founded.
Back to the beginning
In December 2000, Don Adam faced a puzzle. He had been asked to lead an initiative to jump-start a stalled Vancouver Police Department (VPD) investigation into the disappearances of 27 women from Vancouver’s Downtown Eastside, a notorious hangout for sex trade workers and drug users.The facts of the case were as follows: The VPD was looking for a serial killer — the same man who behavioural science research indicated had murdered another three women in 1995, dumping their remains off logging roads in the Fraser Valley. This “Fraser Valley killer” had left his own DNA at the crime scene, and the VPD was using that DNA profile to eliminate suspects in the Downtown Eastside investigation. VPD officers reported that no women had disappeared from the Downtown Eastside since 1999. The officers were running a historical investigation, working their suspects hard, but getting nowhere.
“When you’re faced with an enormous problem like this, the first thing to do is (conduct) an investigation of the investigation,” says Adam. “Don’t try and find the killer. Try and find out whether you believe (the previous investigators) followed a methodology that will ensure all your bases are covered.”
Adam and a small review team of RCMP and VPD officers spent the next several months assessing the foundations of the two-year-old VPD investigation. They took nothing for granted, and as such, they uncovered a few structural flaws.
False logic
The first weak point was the link between the Downtown Eastside disappearances and the Fraser Valley killings, says Adam. The Valley women had been dumped along accessible logging roads, whereas the Downtown Eastside women had all disappeared without a trace.“If you (as a killer) have had 27 completely successful disappearances, why would you leave these three (bodies) to be found, when, by putting in a little extra effort to take them another three feet and roll them down a ravine, they could have been gone forever?” says Adam. “It didn’t make sense.”
The review team thus rejected the behavioural science link as too limiting on the investigation. “We decided not to accept that our killer was (also) the (killer) from the Fraser Valley,” says Adam. “That meant we were going back to square one.”
But the team was further ahead than they could know at the time. Pickton, who had actually been eliminated as a suspect based on the Fraser Valley DNA profile, was now back in the suspect pool — and flagged as such on Canada’s national police computer system. One year later, Cst Wells would see that flag while preparing his firearms search warrant, and he would contact the MWTF to stand by during his search on February 5.
“When you’re faced with an enormous problem like this, the first thing to do is (conduct) an investigation of the investigation."

Widening the net
The review team also questioned the decision to run a historical investigation. Assuming that the killer had gone to ground would completely close the door on the possibility that he was still active in some way — any way — even if it wasn’t murder.“When killers are operating in the here and now, they will be making mistakes,” says Adam. “(As an investigator), you need to be very tuned in to any leads on similar types of offences — in our case, attempted abductions and new missing (women) — so that you can insert your task force into those investigations immediately.”
The review team wasn’t willing to accept the logic of a historical investigation until it had reviewed every bit of evidence associated with the case. Therefore, when the MWTF was officially launched in September 2001, investigators were already operating on two fronts: on one front, a section was reviewing and culling the historical files; on the other front, a section was working in the present tense, actively seeking new leads or fresh evidence that might unveil the killer. In hindsight, this multifaceted approach paid off.
Closing the noose
Throughout 2001, task force members identified another 18 women who had disappeared from the Downtown Eastside since 1999. Two of those women would provide the MWTF with its break on the farm on February 5. When human remains were unearthed months later, the victims’ identities were confirmed through familial DNA profiles that the MWTF had persevered in gathering and submitting to the Vancouver Forensic Laboratory’s DNA Data Bank.Task force members were also actively investigating leads on sexual assaults, other assaults and abductions within their victim pool. The unit re-submitted old exhibits for DNA testing, became involved in new offences linked to their key suspects, and alerted municipal police forces to their expanded focus — hence their attendance at Wells’ weapons search on February 5.
Even without the break at the farm, says Adam, the team was slowly closing in on Pickton. Task force members were out on the streets, tracking sex trade workers and looking for any hint of suspect activity. The team knew that victims were still being taken from the Downtown Eastside at a rate of approximately one every six weeks, and investigators were closely examining the habits and acquaintances of the missing women. Prior to February 2002, members had identified a female subject who had transported a recently missing sex trade worker out of the city. Later, after the February 5 search, investigators would closely link this female to Pickton.
“The way we were operating, we absolutely would have got Pickton,” says Adam, noting that the entire MWTF team was focused, committed and willing to think critically from the get-go.
“The fact that Nathan Wells, a young member obtaining his second search warrant, got us on the farm — that was luck. The fact that we were there on the farm (in the first place), that’s good policing. We positioned ourselves to win.”
Sit back and assess every step you take until you’re 100 per cent certain it won’t cost you down the road.
Lessons for the future
At the end of the day, Adam has one piece of advice for any new task force faced with similarly complex missing persons’ cases: sit back and assess every step you take until you’re 100 per cent certain it won’t cost you down the road.“In these tough investigations, we (as investigators) are desperate for anything to help give form to the investigation,” says Adam. Behavioural science, past investigative decisions, investigators’ “instincts” — all can provide form and direction, but they must be backed by sound methodology, says Adam. Otherwise, you risk casting your net too shallow, or in the wrong pond, and your investigation will sink while the target swims away.
*In December 2007, Pickton was convicted of six counts of second-degree murder. He awaits trial on 20 counts of first-degree murder. A 21st count was terminated by the trial judge.
