Police used photo lineups with images that included other people involved in the investigation into Vancouver's missing women along with Robert William Pickton, the jury heard Monday.

During his second day under cross-examination by defence lawyer Richard Brooks, Vancouver police Det.-Const. Mike McDonald continued to face questions about others who were considered persons of interest by investigators in the case. 

McDonald told the B.C. Supreme Court in New Westminster that the photo lineups included Pickton's younger brother Dave, Scott Chubb and Pat Casanova.

The jury has heard in earlier testimony that Casanova was one of three people other than Pickton who had been arrested but never charged in connection with the missing women investigation.

Chubb was the police informant who prompted the initial firearms search on the property.

McDonald also testified there were other people placed under surveillance in connection with the investigation.

Pickton is being tried on six of 26 charges of first-degree murder in the deaths of missing women from Vancouver's Downtown Eastside, with a second trial to be held later. He has pleaded not guilty to all charges.

Officer says Pickton's brother not a suspect

During testimony Monday, McDonald clarified that Pickton's brother Dave is not a suspect in the missing women's investigation.

"At this moment, to the best of my knowledge, he is not being investigated at this moment," McDonald said, when questioned by Crown attorney Jay Fogel.

"And to your knowledge, is there any evidence linking Dave Pickton to any crime related to any of the missing women?" Fogel asked.

McDonald responded that to his knowledge Pickton was not.

Last week, McDonald testified Dave Pickton was still being investigated in connection missing women from Vancouver's Downtown Eastside.

Monday, jurors also heard testimony from Vancouver Const. Mark Christensen, one of two officers who discovered the remains of Mona Wilson. He detailed the discovery of their remains and matching the fingerprints with Wilson's.

Pickton is charged with Wilson's murder, as well as the murder of Sereena Abotsway, Georgina Papin, Brenda Wolfe, Andrea Joesbury and Marnie Frey.

Talked to clergy

Jurors also got some insight Monday into how Pickton has spent some of his time in custody.

Brooks questioned McDonald about several conversations he had with two clergymen from North Fraser Pretrial Centre, where Pickton has been in custody for just over five years.

McDonald took notes on a conversation he had with clergyman Harold Krahn on Jan. 24.

Using his notes, McDonald said Krahn had seen Pickton recently and his "spirits were good" in the days leading up to his trial and he had "put his agricultural course into hiatus" while heading to trial.
