Patricia Anne Riggs' body was found on August 21. (Facebook)  The 15-year search for murdered Queensland mum Patricia Anne Riggs ended when a home-owner started building a retaining wall in his backyard and discovered skeletal remains.  Ms Riggs, a mother of four, went missing on September 30, 2001 from her home in Janet Street, Margate.  On Sunday, her remains were found in the backyard of the home she had lived in with her husband Edmund Ian Riggs, who had since moved to Dickie Beach.  After a three day search by police, which ended Tuesday, Riggs was charged with murder and interfering with a corpse.  Sitting ashen-faced and wearing a Broncos shirt, Riggs fronted Redcliffe Magistrates Court on Wednesday.  He was remanded in custody and his case was adjourned until November 30.  Mr Riggs' solicitor Michael Reddy told reporters he did not have time to consult his client "at length" before his appearance.  "(He's) a little bit stressed as you could imagine," he said.  Detective Senior Sergeant Ben Fadian said the reaction of Ms Riggs' family to the news was mixed.  "They are in some way relieved ... but there is a court process they have to go through," Det Sen Sgt Fadian said.  Former next door neighbour Frances Wing says she always suspected the missing mother of four would be found in her own backyard.  Ms Wing, who has lived in Janet Street for more than 30 years, says Ms Riggs, was a down-to-earth person who intended to be a swimming coach before she went missing on September 30, 2001.  Ms Wing said there had been a lot of police activity in the past few days and searchers found the remains near the back fence.  "The police had been back and forward looking; we always suspected it might be there," Ms Wing told reporters outside her home.  "I always said it was a chance it was in the garden."  She had only fond memories of Ms Riggs, who was 34 when she was reported missing.
