The nation is reeling from a series of mass shootings, including two in California in less than 48 hours, leaving at least 18 people dead and 10 others wounded. The latest occurred Monday afternoon in the small city of Half Moon Bay, where a 66-year-old gunman killed at least seven people in two locations, both of them farms, in what police said stemmed from a workplace dispute.

The massacre in Half Moon Bay came on the heels of the mass shooting in Monterey Park, where a 72-year-old gunman killed 11 people and wounded nine more at a ballroom dance studio amid a Lunar New Year celebration on Saturday night. All 11 of those killed were identified on Tuesday.
