However, as Newport police pointed out in an update issued Friday, the officers had broken off the chase before the suspect crossed into Pennsylvania.
According to Newport police, officers had tried to stop the driver of an Audi, identified as 29-year-old Delaware resident Keith Campbell, around 1:12 a.m. Wednesday on Route 4.
Campbell failed to stop, and police gave chase. Newport officers were joined by Delaware State Police troopers as the pursuit continued onto Interstate 95 northbound.
However, police say, the pursuit was called off near the Christiana Mall in Delaware after Campbell's driving became too reckless and endangered other drivers.
Police say the pursuit was called off after about five minutes.
It was around 1:45 a.m. when Campbell's car slammed into an Acura SUV at 7th Street and Packer Avenue in South Philadelphia.
Campbell was found with stab wounds. Investigators say a knife and a "rambling" note were found in his vehicle. It's possible Campbell stabbed himself, police say.
Joseph Ferry, 36, of Philadelphia and his 35-year-old fiancée, Kelly Wiseley of Glenolden, Pa., were killed.
The couple had just gotten engaged on Christmas.
Thirty-one-year-old Dennis Palandro of Morton, Pa. was also killed.
His 30-year-old wife, Nicole Palandro, remains hospitalized.
The two male victims were members of the South Philadelphia String Band. Palandro's father is a captain of the band.
Campbell has been charged with three counts of homicide by vehicle and other offenses.
