The first-degree murder charge is based on the forcible confinement allegations, Kavanagh said. The charge, often used in planned and premeditated murders, is also used when someone is killed while they are being forcibly confined.
“He entered that vehicle of his own free will, but he was not allowed to leave, therefore forcible confinement is the proper charge,” Kavanagh said when asked about the charge.
