OKLAHOMA CITY (AP) -- Several convicted killers are up for parole including one who killed his family, one who killed his mother and one who killed a man on Christmas Day 1968.


Being considered for parole are Kenneth Ray Castleberry who was convicted of killing his wife and two children in 1972 and is serving three life sentences. Also up for parole is Mark Engers who was convicted in 1987 of killing his mother Dorothy Engers. And Harley Ed Dickerson is up for parole from a life sentence. Dickerson was convicted of killing two people including Gilbert Walters. Walters was killed as he walked home from work about 1 a.m. on Christmas Day 1968. Dickerson's parole hearing is for the shooting death of Wilbur Ward three days after Walters' murder.


The parole board will also consider the case of Calvin Barnett whose death sentence was commuted to life in prison for the 1974 stabbing death of a Tulsa man during a robbery.
