A civilian oversight board has found that eight Los Angeles police officers who mistakenly opened fired on two women during a manhunt for rogue ex-cop Christopher Dorner violated department policy.

The Police Commission's decision Tuesday follows an earlier settlement in which the city agreed to pay the pair $4.2 million.

Margie Carranza and her then 71-year-old mother, Emma Hernandez, were delivering papers around 5 a.m. on Feb. 7 when LAPD officers guarding the Torrance home of a target named in an online Dorner manifesto blasted at least 100 rounds at their pickup.

Hernandez was shot in the back and Carranza had minor injuries.

Dorner had vowed warfare on Los Angeles police officers and their families for what he called an unfair firing.
