Please tell me if there is a credible source to the post that has been repeated on various sites, claiming "the ammo used to kill Domingos/Edwards, Winchester-Western Super X .22 LR, right hand twist with six lands and six grooves, was the same kind used by Zodiac at Lake Herman Road on 12/20/68."
The person who originally posted this also posted an old Vallejo Times Herald article which supposedly verified this, but the article said Det. Baker said there was no info on the ammo.

Thanks for your help.
