HARRISBURG - State corrections officials say that more than 1,100 inmates have returned to Pennsylvania prisons after being temporarily housed in Michigan for more than a year.

Corrections Secretary John Wetzel announced yesterday that a slight decrease in Pennsylvania's prison population combined with expansion projects allowed the convicts to return.

State prison officials moved inmates to Michigan and Virginia in early 2010 to alleviate overcrowding.

About 1,000 prisoners continue to be housed in Virginia. Wetzel says he hopes to return those inmates to Pennsylvania as soon as possible.
