Overview
- A road‑rage confrontation on Sunday escalated when a U‑Haul allegedly rammed a BMW on an I‑76 exit ramp and two other vehicles boxed the driver in.
- Police say Samuel Marquez, 40, then exited the U‑Haul, punched the driver and stabbed him with a box cutter; medics took the victim to Lankenau Medical Center for treatment.
- Lower Merion officers located the U‑Haul and detained a passenger at a Sunoco station while Radnor police later arrested Marquez sitting on a park bench in Bryn Mawr.
- Authorities recovered a silver box cutter on Marquez and found a second knife on County Line Road that is being tested; Marquez has been charged with aggravated assault, terroristic threats and related counts and was denied bail.
- Court records show Marquez was previously wanted in a 2022 Royal Farms armed‑robbery probe and investigators say the case remains active with possible additional arrests and a preliminary hearing set later this month.
