LAKEVILLE — Police in a Twin Cities suburb are investigated whether the death of a woman found outside her house was related to the cold weather.

Lakeville authorities said family members found the woman, in her 30s, about 4 p.m. Tuesday. Police say there was evidence of hypothermia before she died. An autopsy is expected to be done Wednesday by the Hennepin County medical examiner’s office.

Temperatures in the Twin Cities have been well below zero this week.
