SAN FRANCISCO — The California Supreme Court has upheld the death sentence for a man convicted of raping and strangling 10 women in Los Angeles. However, the court also reversed his conviction for the death of one victim’s fetus.

The court ruled Monday that an error in presenting evidence meant Chester Turner's second-degree murder conviction in the death of the fetus of a woman who was 6-1/2 months pregnant should be overturned. But the court upheld his conviction and sentence for killing 10 women in the 1980s and 1990s.

Prosecutors have called Turner one of the most prolific killers in Los Angeles history.
