PHOENIX (NBC, KYMA) - Authorities said a man with a criminal history in Arizona has been arrested on a first-degree arson charge in Washington State. Farinacci reportedly told detectives what he'd done and was booked with first degree murder, but in 2012, he took a plea deal for manslaughter and aggravated assault. Documents show his mother Beth expressed anger at sentencing, saying she "felt a second degree murder charge would be more appropriate" since he intentionally shot and killed her husband. The now 37-year-old is facing a first-degree arson charge for reportedly starting the Old Trails Fire in Spokane, Washington. Witnesses told authorities they saw him bending down in the grass in the same area where the fire started.
