(TIME) Five bullets struck a 73-year-old California man, killing him, during a fatal encounter with police earlier this week, authorities said.

Francisco Serna died Monday after a Bakersfield police officer believed the septuagenarian was armed and opened fire while the man was standing in his neighbor’s driveway. Authorities had received a 911 call from a neighbor who felt threatened by Serna and warned police of an armed man.

Bakersfield Assistant Police Chief Lyle Martin said at a news conference Tuesday that Serna had one hand in his jacket pocket and ignored commands to stop walking and to take his hand out of his jacket before he was shot.
