POLICE investigating the murder of a Co Derry woman were last night given more time to question a man about the killing.
Katrina Rainey, aged in her 50s, died from horrific burns outside the farmhouse n Knockloughrim where she lived with her family. She was found inside a burning car parked outside the house on Tuesday at around 5.40am.
Firefighters and the ambulance service attended the scene at Quarry Road and Ms Rainey was taken to hospital.
A former midwife, she is understood to have suffered 95 per cent burns to her body. She died later that evening in hospital.
A 59-year-old man was arrested on suspicion of murder. It is believed he was taken to the burns unit at the Royal Victoria Hospital in Belfast for treatment to injuries to his head and hands.
His injuries are not believed to be serious.
A police spokesman last night said detectives from the Major Investigation Team had "been granted a further extension of 36 hours to question a 59-year-old man arrested on suspicion of murder".
It is the second tragedy to hit the family after Ms Rainey's daughter died in farmyard accident almost 20 years ago.
In July 2002 her six-year-old daughter Heather died when a wall collapsed at the family farm.
Heather's brother and sister, who are two of triplets, were both also injured when masonry fell from a silage pit.
Rev Glen Jordan, the former minister at Knocloughrim Presbyterian Church, described the Rainey's as a "lovely family and totally supportive and kind and helpful".
In a statement, the PSNI asked that the Rainey's be given privacy "as they try to come to terms with such a great loss to their family that will affect every part of their lives".
No funeral details had last night been announced.
