A woman found dead in a St. Paul home Sunday suffered her fatal injuries earlier in Brooklyn Park at the hands of her domestic partner, authorities said Tuesday.

Officers were called to a townhouse in the 1500 block of Jackson Street around 2 p.m. on a report of an overdose, said Sgt. Natalie Davis, a St. Paul police spokeswoman. Upon arrival, the officers found the woman dead in the basement with injuries apparently suffered during an assault.

St. Paul police said Tuesday that their "homicide investigators were able to determine the victim … was assaulted the day before in Brooklyn Park." No arrests have been announced in a case that has Brooklyn Park police as the lead investigatory agency.

A home was searched Monday in the 7500 block of Brunswick Avenue, where investigators "located evidence leading them to believe that the victim had been assaulted by her domestic partner, which resulted in her death," read a statement from Brooklyn Park police, who revealed no details about what they found.

While the Ramsey County medical examiner has ruled the case a homicide, the woman's exact cause of death has yet to be disclosed.

The victim was described over emergency dispatch audio only as a 36-year-old woman. Authorities have not yet released her identity other than to say she did not live in the townhouse where her body was found.

Despite police believing the woman died in St. Paul, the city's 2021 homicide total remains at six because she suffered her injuries in a different city, said St. Paul police spokesman Steve Linders.

Investigators interviewed and released multiple people in the St. Paul house at the time.
