Principles

The commission of a crime does not suspend the rights of privacy of the people who live where it occurred.


After the commission of an offence, your authority to search the scene depends upon:
In the case of a sudden death, the Coroner's Act (B.C.) authorizes the Coroner to search the scene or delegate that function to you.  Therefore, brief the Coroner immediately, and ask for authority to search the scene for evidence of the cause of death. 

Consider the possibility that the people whose privacy you violate when you investigate are parties to the offence.

Examples

There still remains a popular misconception that police can always search crime scenes without getting a warrant.  Your power to search a place depends upon the circumstances.  There is no general power of warrantless crime scene search.

Here are two decisions.  In the first, there was no crime, but there was lawful authority to search a residence without a warrant.  In the second, there was a serious stabbing in a residence, but no lawful authority to search it.

Ms Peacock-McDonald, 2007 ONCA 128 wanted to kill herself.  Police officers took her to hospital where she was detained under Ontario's Mental Health Act.  The doctor's order could hold her not more than 72 hours.  Meanwhile, one officer returned to her house and searched it for firearms.  Although the decision doesn't say, it appears he had good reason to believe that there were firearms present.  He didn't get a warrant.  He found guns.  Defence complained that he should have sought a warrant.  There was time: Ms Peacock-McDonald wasn't released for 2 days.

The officer explained that although she was detained, she could be released at any time simply by "shoring herself up" and denying that she was suicidal.  The court agreed with the officer.  This was a risk which rendered it impractical to seek a warrant, and the search was for her safety and the safety of the public.

Consider, on the other hand, Mr McCormack, 2007 BCSC 1526, who called the police after he'd been stabbed at his residence.  The attending officers also heard from a neighbor that the assailant had a gun.  They searched through the residence for guns and other occupants.  They found blood trails, including one which led to the garage, but they did not find guns nor the stabber.  McCormack became uncooperative, and told the police to leave his residence.  McCormack went to hospital, and the police left the residence.  A senior officer directed another search of the residence for weapons and evidence of the offence.  But he did not seek a warrant because the assailant enjoyed no expectation of privacy in the house.  He also thought that because the house was a "crime scene", police were entitled to search.

The second search found large quantities of drugs in the garage.  McCormack complained that the officers violated his expectation of privacy, and the court agreed.  The first search was justified by the risks to the officers and the public of an armed assailant in the house.  The second search was not.

The senior officer was right about one thing: if the assailant was a visitor to the house, then the assailant enjoyed no expectation of privacy in it.  The assailant would have no standing to complain about breaches of his rights.  But McCormack did, and he had specifically ordered the officers out of his house.

The officers went into the house as trespassers looking for evidence against the visitor, but emerged carrying evidence against the resident.
