Years after the crime, we are expecting to read details about a 2008 murder in Butte that left one man dead and his son charged with killing him.
County attorneys say they will file the affidavit Thursday in the case of Adam Hatfield. The 24-year-old is charged in the death of his father Matt.
Hatfield was picked up recently and had his initial court appearance this week. Deputies have been pretty quiet about what evidence led to the arrest in the cold case.
Thursday's affidavit should shed at least some light on the case prosecutors are making against Adam.
