The woman apparently went about her business after her mother died between 1-3 years ago without informing anyone and leaving the corpse propped up in a chair.
Police said they were investigating the mother's death to determine if it was from natural causes of if an accident or foul play was involved.
The grisly discovery was made after city officials in Mael-Carhaix noted the yard becoming overgrown with weeds, Le Telegramme said Sunday in a translated report. The landlord of the house apparently never visited the woman because the rent was always paid on time.
