THE youngest son of a 55-year-old woman found dead at a townhouse in Sylvania, south Sydney, has been arrested.

The body of Linda Connors was found in her blood-soaked bed this morning by one of two sons she shared her Florida St home with.

It is understood Ms Connors had sustained extensive injuries to her body, including a significant head injury, and had been wrapped in a blanket.

Officers were called to a house on Florida Street about 6.45am after receiving calls about a person’s welfare.

Miranda Police Superintendent Michael O’Toole said a number of items had been seized in connection to the case, including a pitchfork and a crossbow, the Daily Telegraph reported.

Police arrested Ms Connors’ youngest son, 28-year-old Nathan White, on the Princes Highway at St Peters, not long after her body was found. Mr White was taken to Newtown police station where he is currently being questioned.

Supt O’Toole also said it was too early to tell when Ms Connors was killed. He said investigators had not ruled out the possibility she died on Mother’s Day.

“Upon arrival this morning police located the body of a woman in her bed,” he told reporters at a press conference.

“The woman resided with her two sons — a 28-year-old and a 31-year-old.

“The eldest is with Miranda police assisting with inquiries. He is not in custody ... he is very distraught as he was the one who came across the incident and called police to attend.

“The youngest son was pulled over by Miranda police in St Peters shortly after the incident ... A crossbow and a number of items were taken out of that vehicle.”

Police sources told The Telegraph investigators believed the pitchfork to be the murder weapon but were also investigating if the crossbow was used.

Next door neighbour 29-year-old Janine McCrohon told the Daily Telegraph she was “absolutely shocked” at Ms Connors’ murder.

“You don’t think that sort of thing would happen next door,” she said.

“I went to school with the youngest son, he was a year or so below me at school. The woman’s car isn’t here.

“We saw police leave the scene with her oldest son this morning. But her youngest son always says hello to the kids and the neighbours. He was the nice one in the family.”
