Search Warrant Requirement Traffic Crash After the Fact
Situation: Police Department "A" investigates a crash where the driver at fault is permanently paralyzed, minor injuries to another vehicle's occupants. "A" does not pursue charges on this paralyzed driver. The mother of this at fault driver raises all kinds of cain due to insurance issues saying her son was never driving "his" vehicle at the time of the crash. This mother is a former employee of "A" and says there is an inappropriate and biased investigation done. "A" then requests police department "B" to conduct an independent investigation and to conclude who was driving the kids car.
Dept "A" impounds the car in a lot that is not secured during the day, accessible by anyone walking by. The request for dept "B" comes 20days after the crash. Investigators for "B" are never told about any pre-exsisting search warrant or verbal/written consent from the vehicle's owner. Also note this department is not even within the same District Attorney's jurisdiction. Investigators knowing this can easily lead into a civil action if not a criminal one later even though they are told no one is being charged ask for a search warrant to collect any evidence supposedly in this car. Their commander orders they collect evidence out of this vehicle, even after they advised the "boss" there is no "Crash Exception" to a search warrant. This boss thinks that a vehicle crash has no reason to have a search warrant be issued to collect evidence. These investigators collect this evidence and leave.
Question: Did Dept. "B" violate the vehicle owners constitutional rights under the fourth amendment or were they acting within their legal authority when they collected possible evidence that can be used later at a civil or criminal trial? I know the officer's ordered to do the act will have qualified immunity status, but should this dept have had the proper search warrant? And if the investigator in charge that asked about the warrant be disciplined later for insubordination does he have an out?
Big one for my first question around here.
