A pre-trial hearing is being held in the Craig Rideout murder case.
A judge must decide whether statements by some of the defendants can be used by prosecutors as evidence at the upcoming trial.
Rideout's estranged wife, Laura, two of their adult sons, and her boyfriend -- Paul Tucci -- are charged with murder.
Craig Rideout was apparently killed at his Penfield home last July. His body was found in a wooded area in Yates County.
Some of the defendants have asked to be tried separately.
