LOS ANGELES—A man has been sentenced to death for the 2006 killing of his girlfriend, who was stabbed 172 times.

Los Angeles Superior Court Judge James R. Dabney gave the sentence Friday to 49-year-old Ricky Rene Madison.

Madison had previously been convicted of manslaughter in the 1981 stabbing death of another girlfriend, one of nine previous felony convictions.

In May he was convicted of first degree murder for the 2006 killing of girlfriend Aysha Sly.

The jury did not find that Madison personally wielded the knife, but was responsible for Sly's death. Another man charged in the stabbing was acquitted.

The jury also found true the special circumstance allegation of murder involving the infliction of torture.
