"My bedroom's up there. I didn't hear anything," said resident John Musilli.
And yet sometime over night, police say more than 30 cars vandalized over a six block area around 18th and Bainbridge Streets. Neighbors in the Graduate Hospital area of South Philadelphia woke up to go to work and were met with deep scratches in their paint and flat tires.
Lauren Summers expressed her frustration, saying, "It's going to be $1,000 worth of damage fixing something for kids to have fun."
"Well the gentleman over here was the one who informed me my tires are flat," said Anna Sharkansky. "I kind of felt stupid, I got out of my car and there they were."
As her car was loaded onto a flatbed and towed, detectives walked through the neighborhood taking pictures and assessing the damage. The report showing tire after tire slashed - some cars hit more than once.
Residents are commiserating over the frustration, the futility.
Matt Goldstein summed up the emotions of all the victims, saying, "I don't understand why anybody would do this. To go down the street and slash tires, I don't understand what they get out of it."
Kim Cahill added, "What's wrong with you? Why are you doing this to people who have done nothing wrong to you?"
Friday afternoon police released surveillance video showing four suspects walking along the 1700 block of Catherine Street.
If you have any information about the identity or whereabouts of the suspects you are urged to contact police. To submit a tip by telephone, dial 215-686-8477, or text a tip to PPD TIP or 773847.
