Walked by over lunch today. Forensics took a small chest freezer from the house and loaded it into one of the Forensics trucks and took it away.
Whoa
Just jumping off that idea - I can't imagine that the police would be allowed (by the Crown Attorney) to have plumbers (citizens) enter a crime scene to replace plumbing until they were 100% done and ready to release the scene back to the homeowner. Their warrant has several more days on it (I can't remember how many, but they were recently given thirty days). The risks of doing so would be enormous - possible contamination of the scene by the civilian plumbers, comes to mind!
Would they be allowed to bring in the plumbers as experts on where pipes are in the ground (eg: where to dig?) would they not have their own experts to do that sort of consult? Maybe they used the plumber to drop a camera down into the pipes for better visuals?
The only lines in the ground would be to the city sewer and water and for those they would have city workers.
My guess is they need some plumbing removed, that requires the skilled tradesmen to do.
