The man who Duluth police believe shot and killed his sons, his wife, and his ex-girlfriend before taking his own life apparently suffered from schizophrenia, and things were getting worse.

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

He said he changed his medication a few days ago and since then ‘voices were telling him that Trump was going to take over the world, so he should kill his family to protect them.’

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

The report states that he made some kind of suicide threat a year and a half ago.

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