Garry Weigand, 56, died at the Metropolitan Remand and Reception Centre at Silverwater on October 18, less than three weeks after the body of his girlfriend, Sandra Deacon, was found in the backyard of his Budgewoi home with severe injuries to her head and face.

Police and Corrective Services NSW have not revealed how Mr Weigand died, but denied that he was assaulted while in custody. Mr Weigand was on a disability pension at the time of his death, and met Ms Deacon at a local dance for people with intellectual disabilities.

‘‘He was alone in a cell and there are no suspicious circumstances surrounding his death,’’ a Corrective Services NSW spokesman said.

Both deaths are now the subject of investigations for the NSW Coroner’s Office. The police brief of evidence into Ms Deacon’s death on September 30 is due to be handed to the Coroner’s Office on December 2.

A police and Corrective Services investigation of Mr Weigand’s death will be handed to the Coroner’s Office by January 23.

Criminal proceedings against Mr Weigand will formally end on November 26, when he was next due to appear at Wyong Local Court.

Ms Deacon’s funeral was held last week, nearly six weeks after police discovered her body in the backyard of Mr Weigand’s house in Sonoma Road at Budgewoi with a severely disfigured face and head. Police investigations included whether the injuries were inflicted by an axe.

Police were called after a heavily intoxicated Mr Weigand was found by an acquaintance at a nearby house shortly after midnight on October 1.

Residents of the quiet Budgewoi street where Mr Weigand has lived in his late parents’ house for at least two decades were shocked by Ms Deacon’s death, and shocked and saddened at news of Mr Weigand’s death.
