McCulkin killers launch separate appeals

Vincent O'Dempsey is appealing his convictions for the murders of Barbara McCulkin and her two daughters in 1974.

O'Dempsey was last month found guilty by a Brisbane Supreme Court jury of taking Mrs McCulkin, 32, and her daughters Vicki, 13, and Leanne, 11, from their Brisbane home on the night of January 16, 1974 and killing them in bushland near Warwick.

A notice of appeal was filed with the courts on Thursday for three counts of murder and one of deprivation of liberty.

Garry Dubois, who was found guilty in November 2016 of the children's murder but Mrs McCulkin's manslaughter, has also launched an appeal bid against his convictions.
