Grenninger gets 30 years for child porn
WILLIAMSPORT A federal judge has sentenced a Castanea man to 30 years in prison for a child pornography case, calling him a “serious threat to society.”
U.S. Central District Judge Matthew W. Brann on Tuesday gave Michael S. Grenninger, 38, the maximum sentence, saying there is a need to protect children.
Grenninger pleaded guilty in February 2020 to producing child pornography.
