DepartmentCrime and Disaster Scene Integrity - 2406.5 SEARCHES
Officers arriving at crime or disaster scenes are often faced with the immediate need to search for
and render aid to victims, and to determine if suspects are present and continue to pose a threat.
Once officers are satisfied that no additional suspects are present and/or there are no injured
persons to be treated, those exigent circumstances will likely no longer exist. Officers should
thereafter secure the scene and conduct no further search until additional or alternate authority
for the search is obtained, such as consent or a search warrant.
406.5.1 CONSENT
When possible, officers should seek written consent to search from authorized individuals.
However, in the case of serious crimes or major investigations, it may be prudent to also obtain
a search warrant. Consent as an additional authorization may be sought, even in cases where a
search warrant has been granted.
406.6 EXECUTION OF HEALTH ORDERS
Any sworn member of this department is authorized to enforce all orders of the local health officer
that have been issued for the purpose of preventing the spread of any contagious, infectious or
communicable disease (Health and Safety Code § 120155).
