A pig farmer accused of being Canada's worst serial killer was found guilty of second-degree murder in the deaths of six women Dec. 9.

Robert "Willie" Pickton was on trial for the first six of 26 murder charges for the deaths of women, most of them prostitutes and drug addicts from a seedy Vancouver neighborhood.

Second-degree murder is a lesser charge that means a murder was not planned. First-degree murder, which means a murder was planned, also carries a mandatory sentence of life in prison but does not offer parole eligibility for 25 years. Pickton has been charged in the slayings of 26 women, but almost 40 others are on a police list of missing women. The investigation into their disappearances is ongoing.

Prosecutors said Pickton will be tried on the 20 other murder charges later, but no date has been set.
