Boston Police say a woman was found stabbed to death in a River Street house near Lower Mills early on Sunday morning.

A preliminary report from BPD says officers assigned to District B-3 — and emergency medical responders from Boston EMS— were called to an apartment inside a three-decker house at 85 River St. around 12:40 a.m. on April 20.

"Upon arrival, officers located an adult female victim suffering from multiple stab wounds," a police account says. "The victim was pronounced on scene."

Homicide detectives are investigating the death investigation, according to BPD.
