DULUTH, Minn. – Police, looking for a man for the shooting deaths of his ex-womanfriend and their teen-age son, found him dead in another house across town, apparently by suicide, as well as the bodies of his wife and another son. The total death toll was five:

> Anthony Nephew, age 46, whom police said had a “pattern of mental health issues.”

 > Erin Abramson, 47, with whom Nephew had had a relationship and a son.

> Jacob Nephew, 15, the son of Anthony Nephew and Erin Abranson.

> Kathryn Nephew, 45, the current wife of Anthony Nephew.

> Oliver Nephew, 7, the son of Anthony Nephew and Kathryn Nephew.

Police Chief Mike Ceynowa said investigators were still were working to identify what triggered the shootings. He noted that police had had occasional encounters with Nephew over the years. On Thursday he had failed to show up for work across the harbor in Superior, Wisconsin. A co-worker called Duluth police to check on his welfare. About 2:10 p.m. police found Erin Abramson and the 17-year-old son dead from gunshot wounds in a west Duluth house. Police went to Anthony Nephew’s address a few blocks away in the Oneota neighborhood and surrounded the place. When they entered, officers found his body and those of  Kathryn Nephew and the 7-year-old son.
