The accused murderer of Philadelphia Police Officer Chuck Cassidy was tracked down and arrested in Miami yesterday, ending a weeklong manhunt that involved hundreds of local and federal law enforcement officials.

John Lewis, a 21-year-old with a record of drug offenses, was caught after a staff member at a Miami homeless shelter recognized him from his wanted picture.

Lewis allegedly killed Cassidy during an attempted armed robbery of a Dunkin' Donuts in North Philadelphia last Wednesday.

The incident caused a lockdown of over 50 schools across Philadelphia, including La Salle University, as police searched for the killer.

Detectives flew down to Miami yesterday after learning that Lewis had boarded a bus to the city.

Cassidy's funeral is scheduled for today.
