Police are probing gang connections in Sacramento, Calif., Monday after a late-night shooting left four people dead, including the shooter. The attack, which police say they first looked at as a home invasion, was likely not “a random act,” police spokesman Michelle Gigante told reporters. “It’s still early. At this point we’re trying to figure out what happened.” The victims were members of Sacramento’s Hmong community. A man who was known as a shaman among the Asian immigrant community was killed, as were his wife and one other person. According to a spokesperson for the Hmong community, the couple’s son shot and killed the assailant.
