Brian Malley, 55, is charged with the first-degree murder of Vicky Shachtay.
The 23-year-old woman was killed last November after a package that was delivered to her Innisfail home exploded.
She was confined to a wheelchair after a car accident in 2004.
A three-week preliminary hearing is to begin next Sept. 9 in Red Deer court.
Malley has been out on bail since June.
Shachtay is survived by her seven-year-old daughter. (CHUB, CKGY)
