Public safety officials in Lewiston and Auburn were looking into two unattended deaths reported within a half hour of each other Sunday evening.

Lewiston police and firefighters were called to 23 Champlain Ave. in that city about 6:55 p.m. after a visitor there found a woman slumped over a sink. She had no pulse, responders were told, and blood in the sink was dry, indicating the death probably had occurred some time ago.

At 7:25 p.m., Auburn firefighters and police were called to 67 Whitney St. in that city by a visitor who said a man living in the apartment was found white, cold and lifeless on a futon.

In Maine, unattended deaths are investigated by police to determine whether foul play was involved.

The names of the dead won’t be released by police until they’ve notified family members of the deceased.
