An Isabella County man is in jail for threatening to kill his mom and later, his entire family.
The investigation started Friday when troopers say the 40 year old Blanchard man threatened to get an AK 47 and shoot his mother.
He was arrested Saturday, then released.
Sunday, troopers learned the suspect was threatening to kill his mother again, and made a statement he might wait until Christmas to kill the entire family.
He was arrested again early this morning and will be held until he appears before a judge.
No weapons were found in his home.
