UPDATE: The suspected shooter in a murder of a Pennsylvania Wildlife Officer has been apprehended. The suspect, Christopher Johnson, has a laundry list of other convictions including burglary convictions and a 2005 guilty plea to a charge of fleeing an officer and endangering the welfare of children.

Police are on the lookout for a 27-year-old man suspected of shooting and killing a Pennsylvania Wildlife Officer last night about 10:30 local time in Adams County.

The Gettysburg Times reports that police are searching for Christopher Lynn Johnson, believed to have shot the game warden with a large-gauge shotgun after several shots were fired in Freedom Township last night. Johnson may be armed and should be considered dangerous, say police. He is believed to be driving a blue 1999 Chevrolet 4×4 extended-cab pickup with Pennsylvania plates YWC 7472.

According to reports, police were summoned to the 300 block of Schriver Road after residents reported gunshots in the area. Seven police units were dispatched, and shortly after their arrival, this ominous report was delivered over the radio: “Officer down…”

A medical helicopter was called, but it was cancelled after reports from the field indicated “too much trauma for the air.”

Police say Johnson may have been wounded in the encounter with the game warden and may try to seek medical attention.
