A Newton man was charged with assault in connection to the death of his wife Saturday evening, according to the Middlesex District Attorney’s office.

Richard Hanson, 64, was charged with assault with intent to murder and assault and battery with a dangerous weapon on Saturday. Hanson allegedly fatally assaulted his wife, Nancy, in their Brookline Street residence Saturday evening, officials said.

Police received a call from a juvenile inside of the Brookline Street home just before 8:30 p.m. Saturday night and found Nancy Hanson suffering blunt force injuries, officials said. She was taken to Brigham and Women’s Hospital where she was then pronounced dead.

The Office of Chief Medical Examiner ruled her death a homicide caused by blunt force trauma. She was 54.

A restraining order was issued against Richard Hanson in the Newton District Court on July 13, officials said. Newton Police were attempting to serve the restraining order prior to the incident Saturday evening.

Hanson is scheduled to be arraigned at Newton District Court on Monday and is being held without bail, officials said. The investigation remains ongoing, according to officials.
