A SERIAL killer known as "The Butcher" murdered 49 women, ground up their bodies and fed them to his pigs - and may even have sold human flesh to cops.
On the outside, Pickton, now 68, lived a quiet life breeding pigs on his farm in Vancouver, Canada.
But he was hiding a very dark secret from the world.
Pickton - known as "The Butcher" - was Canada's worst serial killer.
The scruffy loner would lure women to his farm and torture and murder them before feeding the corpses to his pigs.
Pickton picked the women up from Vancouver's Downtown Eastside, several square blocks of squalid hotels, drug dealers and street-level prostitution.
He lured them to his muddy, garbage-strewn farm with promises of money, alcohol and drugs before killing them in various gruesome ways.
There were rumours about wild parties attended by Hell's Angels and suspicious activity at the pig farm, but they were dismissed by local cops - who sometimes bought meat from him.
One woman managed to escape the killer and ran, naked and bleeding, after stabbing Pickton with his own knife in 1997.
But the drug addict was considered unreliable by police and Pickton was not prosecuted.
He claimed she was a hitchhiker who had attacked him.
Five years and unknown deaths later the full, horrifying truth would come out.
Pickton was convicted of six counts of second-degree murder, 20 other charges of first-degree murder were stayed. He was sentenced to life in prison.
His fall began in 2002, when a truck driver told cops he had seen illegal guns in Pickton's trailer home.
Investigators raided his pig farm looking for the weapons, only to find items belonging to missing women.
After his arrest Pickton sat in a Vancouver jail cell and told his cellmate - actually an undercover officer - that his quest to kill 50 women had come up just short.
He said: "I made my own grave by being sloppy. Doesn't that just kick you in the ass now?"
He said that the police were planning on charging him with murdering 49 women.
He bragged: "I wanted one more, make, make the big five O" before claiming the prosecutors' list of 49 alleged victims only had "half" of his actual toll.
Pickton also boasted of being "bigger than the [serial killers] in the States".
The pig farm became the largest crime scene in Canadian history.
A total of 200,000 DNA samples and 600,000 exhibits were seized and forensic experts were forced to use heavy equipment to sift through nearly 300,000 cubic metres of soil.
The cost of the investigation was estimated at more than $70 million.
