A Jury has convicted Christopher Perrien of murdering a couple in Eaton County.
It took jurors four hours to come back with a guilty verdict on Monday.
Perrien killed retired state trooper Michael Greene and his wife Terri in September of 2011 after he had been granted a work release based on a fake document.
The jury convicted him on two counts of first degree murder and two counts of being a felon in possession of a firearm.
He faces a mandatory life sentence when he's back in court May 9th.
