By 1:30 p. m., the water had been pumped out and the investigators without obtaining consent or an administrative warrant entered the residence and began their investigation into the cause of the fire. They quickly confirmed that the fire had originated in the basement beneath the basement stairway. They detected a strong odor of fuel throughout the basement and found two more Coleman fuel cans beneath the stairway. As they dug through the debris, the investigators also found a crock pot with attached wires leading to an electrical timer that was plugged into an outlet a few feet away. The timer was set to turn on at approximately 3:45 a. m. and to turn back off at approximately 9 a. m. It had stopped somewhere between 4 and 4:30 a. m. All of this evidence was seized and marked. They looked through the rest of the house and found a large portion of items had been removed. There were nails on the walls but no pictures. They found wiring and cassettes for a videotape machine but no machine. Ds moved to exclude all exhibits and testimony based on the basement and upstairs searches because they were conducted without a warrant, consent, or exigent circumstances and that they, therefore, were per se unreasonable under the Fourth and Fourteenth Amendments. That motion was denied. Before trial, they again moved to suppress the evidence. The trial court denied the motion on the ground that exigent circumstances justified the search. The court certified its evidentiary ruling for interlocutory appeal and the Michigan Court of Appeals reversed. P appealed.
