Kelly Schiano, identified as Mario’s wife, and Everett Harper, were arrested in February for the premeditated murders on Trails End Drive.
A third suspect, Justin Casagranda, a close family friend, was apprehended as a hired gunman after traveling from Athens, Georgia, to Charlotte County to carry out the killings.
Schiano and Everett appeared for their arraignment on Monday, with their next court appearance scheduled for May 7 at 1:30 p.m. Both are currently held without bond.
