A law enforcement-involved shooting that left a suspect dead following an armed standoff has been ruled justified based on preliminary findings from the TBI. “It was a case of shoot or be shot,” said District Attorney General Lisa Zavogiannis of the initial report from the TBI on the death of Clifford Keller, 34, who was shot and killed by SWAT team members following a standoff on Chestnut Ridge Road in December. “The preliminary report is it was justified, but we have to wait for ballistics to be completed before we can say something final.” Deputies went to the remote location off Viola Highway to arrest Keller on outstanding warrants.
