He is thought to have died three days before his body was discovered. He was found with an electric cable tied around his neck and attached to a shelf above. No violence was apparent.
Police, who found three beer bottles and a liquor bottle, all empty, in the room, believe he killed himself because of depression over his broken relationship with a Thai woman.
They said Mr Burghardt had been with the woman for seven months before she left him.
Before killing himself he had discovered that she had sold a bar that he had bought for her. This was apparently the last straw.
