CHRIS LLOYD wrote about Mary Ann Cotton, the North-East most famous female killer who was sentenced to deal for poisoning more than 20 people (Echo, June 2).

The last home Cotton lived in is in West Auckland on the right hand side of the road as you start going to Toft Hill.

She was imprisoned in the old police station in Bondgate, Bishop Auckland. When she was sent for trial at Durham she was frog marched under escort to the old railway station.

My wife and I were walking round Durham prison to see the main entrance where a murderer from Cumberland was hanged when four warders from the warders club saw us looking for the site where Mary Ann Cotton was buried.

They said that as they patrolled each night the guard dogs refused to go near the area where she was buried.

After a murderer has been buried for 100 years, the bones are removed from prison graveyards.

Mary Ann Cotton’s were dug up but I don’t know the whereabouts of her final resting place.
