Two mass shootings that erupted in different parts of the country this weekend share at least one thing in common — both suspects are Marine Corps veterans of the Iraq War.

Police in Michigan identified Thomas Jacob Sanford, 40, a former Marine, as the lone gunman who killed four people and wounded eight others Sunday after he crashed his car into a Mormon church and began shooting at congregants. Officers shot and killed Sanford at the scene.

A day earlier in North Carolina, authorities charged Nigel Edge, also a 40-year-old former Marine, in a Saturday night shooting that left three dead and eight others wounded after he was accused of driving a boat up to a waterfront bar and opening fire on patrons.

Mr. Edge is scheduled to make his first court appearance Monday on charges of murder, attempted murder and weapons-related offenses.
