A 40-year-old man arrested for a stabbing Sunday on the Blue Route in Montgomery County during an altercation with another motorist was wanted for a 2022 armed robbery in Delaware County, court records show.
Samuel Marquez, of Philadelphia, was taken into custody by Radnor Township police after a brief search Sunday evening that led to the 100 block of East Lancaster Avenue, according to police and court records.
The Pennsylvania State Police were handling the stabbing investigation, the Radnor police said.
“Our thoughts are with the victim and their family,” Radnor police said. No other information about the victim was released.
In 2023, the Upper Chichester Township Police said Marquez was wanted for a Nov. 11, 2022, armed robbery at a Royal Farms convenience store at 3314 Market St.
Court records show that Marquez on Tuesday night was being held at the Montgomery County Correctional Facility because his bail was denied. Court records also show that a bail amount had been set at about $1 million.
Villanova University’s campus was briefly under a lockdown Sunday evening as police searched for the stabbing suspect.
The lockdown was lifted at 6:41 p.m. after the suspect was arrested off campus, according to the university’s alert system. The school issued the lockdown at 6:10 as a “precautionary measure due to the proximity of the search,” the alert said.
NBC10 reported that Marquez was driving a U-Haul as part of a caravan of vehicles when a dispute arose. Marquez allegedly struck the victim’s vehicle, then got out and started hitting the victim. Marquez then got a knife from his U-Haul and stabbed the victim in the back, NBC10 reported.
The Pennsylvania State Police recovered a knife that was being tested as part of the investigation, NBC10 reported.
