MINNEAPOLIS (AP) - 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 say family members found the woman, in her 30s, about 4 p.m. Tuesday. Police say there was evidence of hypothermia before she died. The Star Tribune (http://strib.mn/1aeHni8 ) says 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.
