Three people, including two Mummers, were killed in Philadelphia during an early Wednesday crash involving a Delaware man, who police said was suffering from 15 to 20 stab wounds.

Keith Campbell, 29, of the 200 block of Benjamin Boulevard in Glasgow, had stab wounds across his chest and abdomen, Philadelphia Police said in a statement. News outlets are reporting the wounds were self-inflicted.

Campbell was taken to Thomas Jefferson University Hospital in critical condition.

Philadelphia Police Chief Inspector Scott Small has told other news outlets that investigators found a note inside Campbell's car, which he characterized as "rambling, paranoid, strange."

The Philadelphia Police Department, however, said it would not confirm what Small is quoted as saying because it "does not discuss or confirm any potential evidence before the District Attorney's Office has had the chance to review."

Police were dispatched to the 600 block of Packer Avenue for an auto accident about 1:45 a.m. Wednesday.

Arriving officers said Campbell was the driver of a 2014 Audi that struck a 2015 Acura SUV.

Three of the SUV's four passengers were pronounced dead at the scene. The lone survivor, a 30-year-old woman, was taken to Jefferson University Hospital in critical condition with a broken pelvis and other injuries suffered in the crash.

The people killed in the crash were identified as 36-year-old Joseph Ferry of South Philadelphia, 35-year-old Kelly Wiseley of Glenolden, Pennsylvania, and 31-year-old Dennis Palandro of Morton, Pennsylvania.

Two of the victims in the SUV were members of the South Philly String Band, which posted a statement on its Facebook page:

"On behalf of the officers and members of the South Philadelphia String Band, we are deeply saddened at the loss of our family members.



"We ask you to keep all families in your thoughts and prayers.



"While the Mummers community is a close knit family, we ask for privacy for the families and our organization during this difficult time."

Charges are pending as Philadelphia Police Department's Accident Investigation Division continues to investigate the crash.

Lt. Mark Wohner of the Newport Police Department confirmed they are assisting Philadelphia Police with the investigation.
