Los Angeles (CNN) Melyda Corado, a Trader Joe's assistant manager who died during a shootout Saturday, was killed by an officer's bullet, Los Angeles Police Chief Michel Moore said.

"I am truly sorry," Moore said at a news conference Tuesday. "It is unimaginable, the pain of the Corado family. We share the pain today."

Trader Joe's employee Melyda Corado died in the crossfire between a gunman and police.

Police said the disastrous chain of events started when suspect Gene Evin Atkins shot his 76-year-old grandmother and kidnapped a 17-year-old female acquaintance.

As Atkins fled in his grandmother's car, he fired shots out the back window toward pursuing officers, police said. Authorities said the teen he kidnapped was shot in the head but survived.

Officers did not fire at the gunman during the chase. But after Atkins crashed the car outside a Trader Joe's and continued shooting at police, officers returned fire, Moore said.
