A tragic domestic incident in Minnesota left five people dead in a murder-suicide.

A welfare check conducted at two homes in Duluth uncovered the bodies of four victims, including two juveniles, ages 15 and 7.

Duluth police conducted a welfare check at a home along Tacony Street after the city of Superior requested them to check on one of their employees.

“The welfare check was initiated because of an employee with the city of Superior who was concerned about another employee who had not shown up for work, and that was outside of their character,” said Duluth Police Chief Michael Ceynowa during a Friday news conference.

Inside the home was 47-year-old Erin Abramson and her son, 15-year-old Jacob Nephew. Police said the two died from gunshot wounds.

The “reporting person” told investigators about a person of interest, 46-year-old Anthony Nephew.

Police set up surveillance at Nephew’s home on West 6th Street. A short time later, investigators learned Nephew was married to Kathryn Nephew, and they both lived in the home with their son, Oliver.

A drone was sent inside to look for the suspect.

Inside were Nephew’s wife and his 7-year-old son, both dead from gunshot wounds. Nephew was also found dead. Police said Nephew died from a self-inflicted gunshot wound.

Ceynowa said Nephew and Abramson were in a previous relationship and shared a child. Nephew was known to have had mental health issues, according to the police chief.

Ceynowa said he and the department were sending their thoughts and prayers to the victims’ families and loved ones involved in the “tragic event.”
