Craig Gibson, 36, of Chester, Pennsylvania, died on December 23, 2011. His death occurred in the context of a broader criminal environment that also involved a 2007 street shooting in which Gibson was an eyewitness.

On May 22, 2007, at Patterson and Barclay Streets in Chester, Gibson saw an altercation between Eric Caldwell and two men identified as Rashad Ishmail and James Edward Armstrong. Witness accounts say Armstrong drew a gun and fired in Caldwell’s direction; Gibson left the scene briefly and returned to find Caldwell severely wounded. Armstrong was later charged and convicted in Caldwell’s murder.

Separately, Gibson himself became the subject of criminal investigation and charges alleging he participated in cocaine trafficking and provided privileged police information to help a trafficker evade detection; charges listed included felony corrupt organizations, delivery of a controlled substance, and hindering apprehension or prosecution.

Did anyone in Chester at the time have additional information about Gibson’s activities or the 2007 shooting that could shed light on these linked cases?
