A Colombia Heights man shot and killed his wife, and then himself in a parking lot of an Asia Chow Mein Restaurant Saturday morning, WCCO said. The police say that the couple was leaving the restaurant when the man pulled out a gun and shot his wife in broad daylight, and then took his own life. The Star Tribune said that the man shot his wife after he found out that she had plans to leave him. Neighbors said that the two had frequent arguments, but the shooting was a complete shock. Neither of the two have a criminal background.
