A forensic competency examination found Raulie Casteel fit for trial on charges brought by the state attorney general's office.
The findings were discussed at a hearing Wednesday in Howell District Court.
Casteel faces similar charges in Oakland County. A competency hearing is scheduled for Thursday in Novi District Court in that case. The findings are expected to be the same.
Casteel faces 60 counts in Oakland County, including assault with intent to murder. The AG's office brought a terrorism charge against him.
Authorities say the 43-year-old shot at cars along Interstate 96 in October.
Defense lawyers describe Casteel as college educated with no criminal history.
