Michael A. Hawkins v. United States, 113 A.3d 216

Deputies surveilled Michael Hawkins on a fugitive warrant and observed him enter a parked, running Pontiac Montana with a red backpack on the passenger seat. Hawkins exited and was arrested outside the vehicle; deputies blocked the car and ordered him to sit on the ground.
A deputy entered the driver’s side to turn off the running engine (it is unclear whether the door was open) and smelled a strong odor of marijuana; another deputy opened the passenger door, smelled marijuana, and opened the backpack to find a tin with baggies of a green substance, pills, empty Ziplocs, a digital scale, and a grinder. Keys were later removed and the car turned off.
Hawkins was charged with possession with intent to distribute marijuana and possession of drug paraphernalia; one count (ecstasy) was dismissed. He moved to suppress evidence, arguing the warrantless vehicle entry violated the Fourth Amendment.
The trial court denied suppression based on exigent circumstances; Hawkins was convicted at a bench trial of possession with intent to distribute and paraphernalia and appealed.
On appeal the court affirmed but rejected exigency as the basis and instead upheld the entry under the community caretaking doctrine; it also held the trial court did not abuse discretion under Rule 16 by refusing to force the government to identify specific documents relied upon by its expert.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Lawfulness of warrantless entry into a running vehicle	Hawkins: running engine did not create exigent circumstance; entry violated Fourth Amendment	Government: deputies reasonably entered to turn off engine; exigent circumstances or community caretaking justified entry	Entry was not justified by exigent circumstances, but was reasonable under the community caretaking doctrine; suppression denied
Disclosure of specific documents relied on by government's expert (Rule 16)	Hawkins: government must identify the specific HIDTA report and issue of The Informer relied upon by Sgt. Boteler	Government: Boteler relied on his training/experience and did not depend on a single specific document; produced the materials that informed his opinion	Trial court did not abuse discretion; government met Rule 16 by producing the documents and identifying bases for the expert's opinion
