Authorities are gathering evidence after a July Fourth fireworks explosion rocked a community park in Simi Valley.
The Ventura County Star reports county fire officials finished their evidence-collecting Saturday from the park where some three dozen spectators were injured by shrapnel and flying debris.
A state fire investigator was due in town this week to collect more clues from the site and in nearby Ojai, where a pyrotechnics operator was injured by a premature blast.
