A new report says the 600 shots police fired at the end of a California bank robbery that claimed the life of a hostage were excessive.

Monday's report by the nonprofit Police Foundation found some Stockton police officers only fired their weapons because other officers were shooting, and some opened fire with their colleagues standing right in front of them.

The July 2014 shootout left two of the suspects and a hostage, Misty Holt-Singh, dead. Police have said Holt-Singh was struck by 10 of the bullets officers fired.

Stockton police had requested the review by the Police Foundation. Police Chief Eric Jones said in a statement that the department intends to learn everything it can from the report and use it to improve.
