PHILADELPHIA — Blaring sirens, gunfire and the sound of helicopters rocked Center City late Thursday night after a chance encounter between police and a shooting suspect led to a wild chase that culminated with a cop opening fire on a man.
"I wanted to peek my head out, but I thought something pretty bad was going on outside," said Andrew Westerhaus, 35, who lives a few blocks from where police say the chase ended near 24th and Locust streets.
