Three men wearing masks and gloves tried to hold up Monaco Jewelers Friday morning.
An employee opened fire and hit two suspects, killing them. They're identified as Robert Avery and Desmond Brown, both 39 years old, from Los Angeles.
Two suspects got away in a Toyota Camry. It was originally reported Friday only one suspect escaped.
Investigators are also looking at whether two earlier jewelry store robberies are connected to Friday's.
