5am, Friday: THE local community is reeling over the "highly suspicious" disappearance of a much-loved Coutts Crossing Public School teacher.
Grafton City Tennis Club coach Phil Beckman, one of the last people to see Sharon Edwards prior to her disappearance, said he only saw her briefly on Saturday but there was nothing to suggest anything was amiss.
He said she played competition tennis on Saturday afternoon and came back to the club for a few drinks about 5.15pm.
Having known her for about 20 years, Mr Beckman said it was "way out-of-character" for her to just vanish.
"She's that sort of person that is always reliable... it's just strange," he said.
Coffs/Clarence crime manager Detective Inspector Darren Jameson confirmed yesterday afternoon that police held "very severe and grave concerns" for the safety of the public school teacher.
Mrs Edwards was last seen at her home in Riverdale Ct, Grafton between 10pm and 11pm on Saturday, having dined with a male companion in Grafton earlier that night.
The alarm was raised when she failed to show up for work to Coutts Crossing Public School on Monday morning, and she was formally reported missing on Tuesday.
Forensic teams from Strike Force Burrow, which has been set up to investigate the circumstances of her disappearance, have examined both her house and another property at Neill St, Lawrence.
It is believed a number of items were removed from both premises for forensic examination.
Three vehicles belonging to Mrs Edwards and her estranged husband have also been searched, and police have canvassed the neighbourhoods surrounding the two properties.
Det Insp Jameson said none of Mrs Edwards' social media accounts or personal items have been active since she went missing.
Her estranged husband, a former teacher at Grafton Public School, is assisting police with inquires.
"He has been very co-operative in assisting us with trying to establish her whereabouts," Insp Jameson said.
Anyone with information is urged to phone Grafton Police on 6642 0222 or Crime Stoppers on 1800 333 000.
