GROTON, Mass. (AP) — Authorities say four people were found dead at a Massachusetts home and a suspect is in custody.

Middlesex District Attorney Marian Ryan says police found two women and a man dead inside a home in Groton Friday night and another woman’s body outside. She says they appeared to have died of blunt force trauma.

Ryan says 22-year-old Orion Krause will be charged with four counts of murder. A possible weapon was found. It wasn’t known if Krause is represented by a lawyer.

Ryan calls the slayings “a situation of tragic family violence.” She declined to elaborate.

Groton Police Chief Donald Palma Jr. says the killings weren’t a random act and “the town is safe.”

State police investigators spent hours on the rural street Friday night.
