His attorneys David Bate and Jeffrey Toothaker entered a motion to withdraw as his counsel, citing irreparable differences.
The motion was granted, which will delay Murray's sentencing for some time.
Earlier this year, Murray and Tony Locklear, both of North Carolina, were deemed guilty of murder, elevated aggravated assault and robbery for a Dec. 19, 2017 break-in and double shooting in Millinocket that left one man dead.
Businessman Wayne Lapierre died and his wife, who was shot in the head, survived and was able to call for help.
Locklear was sentenced to life in prison. His daughter, Alexis, testified in Murray's trial and in a plea agreement with the state was sentenced to time served, or about a year, for her role in the crime.
