NORMAN, Oklahoma -- A man convicted of killing two of his sisters and the mother-in-law of one of the women has been formally sentenced to death.

Cleveland County District Judge Lori Walkley handed down the sentence Friday to William Eugene Davis.

A jury returned the death penalty for the 53-year-old Davis on Feb. 19 after finding him guilty of three counts of first-degree murder. Davis was convicted of the Sept. 4, 2007, slayings of siblings 52-year-old Tami Link, her 56-year-old sister Sheila Ellis and Link's 87-year-old mother-in-law, Letannah Bishop.

District Attorney Greg Mashburn says Walkley gave Davis three death sentences and a five-year sentence for assault with intent to kill the husband of one of the victims.

The case will be automatically appealed.
