A man was killed after an exchange with deputies Monday in Laguna Niguel, officials said.

The Orange County Sheriff’s Department responded to a call of a man and a woman involved in a dispute on the 40 block of Coral Sea Lane, where the Seaside at Laguna Heights apartment complex is located.

Deputies arrived and found a man in his 30s who was believed to be armed with a hammer, officials said.

The man was fatally shot during the confrontation, but it is unclear what led up to it.
