We succeeded in partially dismantling a complex claim against a major health care client. The family of a former in-patient resident who died as a result of complications from the COVID-19 virus filed suit, raising claims that the patient was sexually assaulted while in the care of the hospital and a subsidiary ambulance company. Asked to join the defense team shortly before trial, we effectively discredited the plaintiff’s witnesses throughout the plaintiff’s case-in-chief.

Reported Cases:
Significant Representative Matters: In a police shooting case involving a fatality, a unanimous Third Circuit panel affirmed the District Court's entry of summary judgment (on Shane's motion as well), holding that the officers violated no Fourth Amendment right of the decedent. Dispatch relayed news of a 911 call for a stabbing, and two police officers approached the scene, where they were informed by multiple bystanders that the suspect had a gun. Converging toward him, and with the benefit of a body-mounted camera recording, the officers ordered the suspect to drop his gun. While the suspect did so, he inexplicably reached down and picked up the gun again. Heroically and utterly selflessly, the officers held their fire and ordered him again to drop his gun-until the suspect raised his gun and aimed it in the direction of one officer and the suspect's mother, whom the suspect had brutally stabbed (leading to the 911 call from the suspect's terrorized sister). Because the suspect aimed his gun at his mother and/or the police officer, the officers used deadly force against him, and only did so when the suspect raised his gun as though to shoot it. Though the suspect died from gunshot wounds, the District Court and Third Circuit ruled that the officers were entitled to judgment on all claims and dismissed the case. The use of deadly force, while tragic, was wholly reasonable given the facts and circumstances which the officers encountered on the night in question. Estate of Paone v. Twp. of Plymouth, 2026 WL 661978 (3d Cir. Mar. 9, 2026).
