PHILADLEPHIA (CBS) — A man behind the wheel suffering from stab wounds is charged in a deadly head-on crash that killed three people, including a recently engaged couple.

Police say the stabbing victim slammed into their vehicle at 7th and Packer, just before 2 a.m. on Wednesday. Three people were killed, including two Mummers for the South Philadelphia String Band at 28th and Porter.

Janis Benstock worked with Ferry at Settle Down Philadelphia, a realty office in Center City. She said Ferry would often talk about his girlfriend and how he planned to propose.

“I’m sure I’m not the only one, but he told me he bought a ring and was like ‘man, I gotta sell some houses, I just spent all this money on a ring,'” Bernstock said.

The couple already had nailed down a date.

Wednesday night, they were supposed to look at venues. Now, instead of planning their future, family will have to plan their funerals.

Denny Polandro Jr., from Morton, was also killed in the crash. Police say his wife is currently in critical condition from her injuries.

“It’s not right, it’s sad. They’re in my prayers,” said one neighbor.

Last year, CBS3 featured the South Philadelphia String Band as they prepared for a bitterly cold New Year’s Day.

A year later, colorful props lined the exterior, suggesting a typical day after the big performance, but around back, conspicuous black bunting is draped over the string band’s sign, a visible reminder of the deep pain inside their hall.

Police believe 29-year-old Keith Campbell, who was driving a white Audi, crossed the double yellow lines and hit the dark-colored Acura head on. When authorities found Campbell, he had 15 to 20 stab wounds and a knife was on the floor of his driver seat.

Campbell is in critical condition and it’s unclear if he will survive. He has been charged in the crash.
