A south Wales man has died on a railway line close to the spot where his teenage son was killed nine days ago.
The Greening family's home on Church Road in Barry
It is thought that before 52-year-old Richard Greening from Barry died, he had attacked his 32-year-old wife Sarah, possibly with a hammer.
She is now critically ill at the University Hospital of Wales in Cardiff, and police say they are not looking for anyone else.
Mr Greening's 15-year-old son Ben was killed when he was hit by a train on the same stretch of track on 20 September.
The couple's three other children, are being comforted by relatives in the Barry area.
Ben Greening had missed the last train home
A Home Office pathologist conducted a post mortem examination on Richard Greening's body on Sunday.
The cause of death was consistent with being hit by a train, but it is unclear why Mr Greening was on the track.
People living on Church Road in Barry where the family lived said they were stunned by the news.
Neighbour Patricia Hawkins said it came as a total shock.
"I didn't really know them but they seemed okay to me, it's bad," she said.
Another man said it was tragic.
"The family was a good family. The kids in the school are really upset about the deaths."
He added: "It's just sad. Very sad."
An inquest into his death has been opened and adjourned.
Patricia Hawkins lives near the Greening family
Ben Greening, 15, was on the track at Dinas Powys when he suffered multiple injuries and died after being struck by a coal train.
It is thought he'd missed the last train home from Penarth.
British Transport Police are investigating the incident.
Ben was a pupil at St Cyres High School in Penarth.
Head teacher Brian Lightman said the entire school community had been shocked and distressed by the tragedy.
"Ben had many friends in the school," he said.
"Trained counsellors have been helping children to come to terms with their grief.
"The staff, students and governors of St Cyres extend their deepest sympathy to Ben's family."
