The man who Duluth police believe shot and killed his sons, wife and ex before taking his own life apparently had schizophrenia and things had gone downhill.

The report says an officer responded on July 3, after Tony Nephew reportedly held a knife to someone’s throat.

He said he had been given a medication change a few days before, and since then “voices have been telling him that Trump is going to take over the world, so he needed to kill his family to protect them.”

According to the report, he had requested to go to St. Luke. There he told the officer that Russians have been controlling his mind since he was 6 years old.

The report said he had made some kind of suicidal threat a year and a half before that as well.

Police believe Nephew shot and killed his ex, Erin Abramson and their son Jacob, and then his wife, Kat Ramsland and their son Oliver. Their bodies were discovered on Thursday, the 7th.
