A Minnesota dad who ranted against President-elect Donald Trump online shot and killed his wife, ex-partner, and his two sons before turning the gun on himself, according to authorities. The shooter, 46-year-old Anthony Nephew, had a “pattern of mental health issues,” Duluth Police Chief Mike Ceynowa said on Friday — one day after authorities found five people dead inside two homes in the city. Authorities found Anthony Nephew’s ex-partner Erin Abramson, 47, and their son, Jacob Nephew, 15, dead from apparent gunshot wounds inside their home Thursday afternoon, police said.
