Care and handling of forensic evidence was the topic Tuesday during the trial for Cody Allan Legebokoff.
Following a parade of similar witnesses last week, a search technologist from an RCMP forensics laboratory took the witness stand.
Search technologists take evidence gathered by RCMP officers and prepare them for reporting scientists who are qualified to carry out DNA analysis in the search for links between defendants and alleged victims.
Search technologist Kenneth Chan took the court through his handling of finger nail clippings, vaginal and anal swabs and a tampon from Jill Stacey Stuchenko, whose body was found Oct. 20, 2009 in a gravel pit off Otway Road.
He also described the search for blood on a pickaroon - similar to a pickax but with a single pointed end - RCMP had seized from Legebokoff's apartment.
Lawyer Oleh Kuzma is leading the presentation of Crown prosecution's DNA-related evidence. Conclusions drawn from the evidence will form a key basis of the Crown's case against Legebokoff.
In addition to Stuchenko, he is accused of murdering Loren Donn Leslie, 15, Cynthia Frances Maas, 35, and Natasha Lynn Montgomery, 23.
The trial continues today at the Prince George courthouse.
