<p>SAN FRANCISCO — The killer of a pregnant woman can be found guilty of the murder of her fetus as well, even if the assailant did not know the victim was pregnant, the California Supreme Court ruled Monday.</p>
<p>The court's 6-1 decision expands the reach of a 1970 state law that made it possible for prosecutors to charge assailants with the death of a fetus when a pregnant woman is attacked. A similar federal law making it a crime to kill a fetus in the commission of a federal offense was signed into law last week. Both laws exempt abortion.</p>
