Overview
- Prosecutors identified the suspect as Dalton Lee Janiczek, 21, who was arraigned on attempted murder of a law‑enforcement officer, aggravated assault and related counts with no bail.
- Authorities say a Whitpain Township sergeant first tried to stop a white 2021 Mercedes G‑Wagon before a Plymouth officer found it at a DoubleTree lot, where the driver struck the officer four times.
- A second officer was injured when the Mercedes rammed a patrol car; both officers were hospitalized in stable condition, and one underwent emergency surgery.
- Investigators say a Plymouth officer fired at the SUV during the confrontation, and it remains unclear whether the suspect was struck; Janiczek was treated for a head wound before being taken into custody.
- Detectives are reviewing hotel surveillance and body‑camera video, noting the Mercedes had recent police contacts in Montgomery and Chester counties; a preliminary hearing is set for Nov. 4.
