A federal judge has given a 37-year-old prison inmate four life sentences for a pair of Wausau robberies.  Curtis Langlois was already serving a life term for killing Kendrith J. Young.  Federal agents say Langlois murdered Young, then drove to Wausau to stick up a convenience store and a video store, getting about 26-hundred dollars.  Langlois’ 27-year-old girlfriend, Holly Antijunti, has been given a five-year sentence for buying the gun he used in the crimes.  Langlois couldn’t buy it because he was a convicted felon.
