A high-profile Mountie who recently came forward with allegations of sexual harassment in the RCMP has now made sensational new claims about the investigation of serial killer Robert Pickton.

Cpl. Catherine Galliford told CBC News earlier this month about abusive treatment inside the national police force, including sexual advances from several senior officers.

Galliford was the RCMP's spokeswoman during the Robert Pickton investigation and is scheduled to speak at the ongoing inquiry into the case, and told CBC News some of what she will reveal at the inquiry.

Galliford says she saw numerous problems inside the investigation, including investigators who were more interested in padding their paycheques and drinking alcohol than catching a serial killer.

"They would break between noon and 2 p.m. PT to just drink and party and go for lunch, but then they would go back to work on Friday and claim double-time," she said Wednesday.
