A jury in Redwood City, California, has decided that Scott Peterson should be executed for killing his wife, Laci, and her fetus.

Cheers went up outside the courtroom as the jury announced its decision after 11 1/2 hours of deliberations over three days. The jury had two options in deciding the 32-year-old former fertilizer salesman's fate: life in prison without parole or death by injection.

Judge Alfred A. Delucchi will formally sentence Peterson on Feb. 25. The judge will be able to reduce the sentence to life without parole, if he chooses to do so.
