The victims are the driver and passenger in a car rear-ended by a semi on US-127 Tuesday afternoon.
The man police believe is responsible for more than two dozen roadway shootings is now expected to face charges Tuesday in Ingham County.
Last week, prosecutors in Livingston and Oakland Counties charged Raulie Casteel with some 66 crimes, including attempted murder.
Investigators say they matched Casteel's gun to bullet fragments recovered from victims' vehicles.
He's currently behind bars without bond.
