The Arkansas Supreme Court says it won't set aside the conviction and life term given to a Randolph County man in the 1998 slayings of a family of four from Dalton.
Billy Dale Green said a judge should have stopped his 2012 trial at least four times, but justices said Thursday any errors were cured by instructions given to the jury.
Members of Green's family testified Green left his house one night in 1998 saying he had to "clean up a mess" created by his son, Chad Green.
Carl and Lisa Elliott and their two children were killed that night. Billy Green said his son killed the family but that he only helped cover up the crimes.
A jailhouse informant said Billy Green admitted killing the Elliotts' 8-year-old daughter.
