The story so far: Beau Zabel, a 23-year-old aspiring teacher from Minnesota, was thrilling in his new life in Philadelphia. But that life was cut short 42 days after it began.
Like every aspect of the investigation, the grainy surveillance footage was more frustrating than fruitful. Parts were blurry beyond recognition. The killing was offscreen. The killer strolled by, head down, his face just eluding the camera. Like a taunt.
After two dead-end weeks, the footage, retrieved from a seafood stand and an auto garage, was the sole lead in the high-profile murder investigation.
Zabel had moved from his native Minnesota to South Philadelphia to teach math in the public schools six weeks before he was shot in the neck on June 15, 2008, near the Italian Market. He was walking back from his summer job at a Starbucks. He died steps from his new home.
