POTTSVILLE â Some Schuylkill County prisoners will continue to serve their sentences elsewhere, as the commissioners on Wednesday approved an agreement to send inmates to Columbia County in 2021. âTheyâre one of the most active counties,â county solicitor Alvin B. Marshall said of Columbia and housing prisoners from elsewhere. The one-year pact is one of several the county has to relieve overcrowding at Schuylkill County Prison, President Judge William E. Baldwin said. At the last county Prison Board meeting on Dec. 9, Warden David J. Wapinsky said there were 28 inmates at other prisons: 15 in Centre; nine in Northumberland; and four in Columbia.
