Roommates who sued a Maryland county Monday claim police officers illegally entered their apartment without a warrant, detained them at gunpoint without justification and unnecessarily shot their pet dog, which was left paralyzed and ultimately euthanized.

The dog, a boxer mix named Hennessey, did not attack the three officers who entered the apartment before two of them shot the animal with their firearms and the third fired a stun gun at it, according to the federal lawsuit.

The lawsuit seeks at least $16 million in damages over the June 2, 2021 encounter, which started with Prince George’s County police officers responding to a report of a dog bite at an apartment complex where the four plaintiffs lived. What happened next was captured on police body camera video and video from a plaintiff’s cellphone.
