THREE Maryborough siblings have been rocked by the death of their parents in tragic unrelated circumstances.Gail Coomber died when she was hit by a falling gum tree in Maryborough about 3.30pm yesterday afternoon.Less than 24 hours earlier, the body of her ex-husband was found in bushland near Daisy Hill.Wayne Coomber died of natural causes and was found at his campsite on Sing Track, a few kilometres south of Maryborough.The former couple are survived by their adult children - David, believed to be in his 30s, Crystal, 24, and John, believed to be in his 20s.A fourth child is believed to have died of cot death several years ago.In another twist of fate, Ms Coomber is believed to have proposed to boyfriend Jacob Sevenich yesterday only hours before her death.Her daughter Crystal Coomber’s Facebook page yesterday displayed about 10 comments from concerned friends.''Hey girl sorry for your lost (sic) of your dad and mum. I wish I could wind back time for you. But just remember I’m here for you and your kids if you need me,” one friend wrote.Gail Coomber’s brother Richard Logue said his sister was taking a shortcut through Highview Christian Community College grounds when the tree was blown over by howling winds.The Advertiser understands Ms Coomber was returning home with son John after collecting some of her ex-husband’s belongings from Maryborough Police Station.Ms Coomber died when she went into cardiac arrest after suffering serious head and internal injuries.''I’m still in a bit of shock,'' Mr Logue said.''She was a good friend.''John is also believed to be the last person to have seen Mr Coomber alive, on May 25.Mr Logue said his sister and Mr Coomber separated about two years ago while living in Western Australia.Ms Coomber moved home to Maryborough - the town of her birth - and was soon followed by Mr Coomber.But the couple did not reconcile, and Mr Coomber lived alone at his campsite.His body was found by a walker at 4.50pm on Monday.Forensic examiners at the coroners office are establishing how and when he died.Asteria Services chief executive officer Douglas Ball said Ms Coomber, who had worked part-time for the disability services organisation for about 10 years, was a popular member of staff.The Maryborough-based Asteria is a not-for-profit organisation that provides support, education and employment to individuals with a disability and their families.Mr Ball said Ms Coomber briefly visited her workplace during her day off yesterday.''She was quite adept at doing any task that needed to be done,'' Mr Ball said.''She was a really good mentor to our new and younger staff.''It’s a shock to all of us and particularly her co-workers.''She will be sadly missed by all of us,'' he said.
