Two separate shooting incidents in the U.S. have left multiple people dead, including a mother shot by her son in Maine and a Walgreens employee killed in California. In Maine, James Davis III shot his mother and opened fire on passing vehicles, killing another motorist before taking his own life. Meanwhile, in California, Narciso Gallardo Fernandez allegedly fatally shot Walgreens employee Erick Velazquez after expressing anger toward pharmacies. Dedicated police investigations are continuing in both cases as communities mourn their losses.
