Arunkumar, 41, and Malathi, 38, were found dead in their locked rented home on Padavattamman Koil Street, Ambattur, Chennai, on Saturday.
Deaths inside locked homes in dense neighbourhoods can go unnoticed for days. A simple check-in on relatives or neighbours living alone can prevent long delays in getting help.
Check on neighbours or relatives living alone if phone contact stops for more than a day.
