Ayr Advertiser 13th August 1835
MYSTERIOUS DEATH – About 3 o’clock of the morning of Monday 3d inst., Mrs. Lundy, wife of Hugh Lundy, farmer Fenwick, was missed from bed by her husband, who communicated the circumstances to his neighbours and commenced a search for her himself. On failing to find her in the neighbourhood of her own dwelling, the search was abandoned, under the impression that, as she had for some days been purposing a visit to her mother’s house, she might have gone thither. As the morning advanced, however, a labourer, who was proceeding to his work, discovered a corpse in the water of Fenwick, a short distance from Lundy’s house, which, with assistance, he drew out of the pool, and found to be that of the unfortunate woman. The body was sunk by the bush of a cart-wheel tied to the neck by a rope. A precognition has been taken by the civil authorities of the circumstances connected with this melancholy occurrence, which is to be forwarded to Crown Counsel.
The details were sent to Edinburgh to see if a case should be brought. So obviously they thought it was suspicious and not suicide. Hugh was in Glasgow by the following year so maybe he ran off. He was married again that year to Caroline Ballantyne.
