Depressed dad jumped from viaduct.
The body of Brady Thomas, from Barry, was found by dog walkers lying at the foot of the 100ft structure in nearby Porthkerry Park on St David's Day morning.
The 36-year-old, described as "a proper and loving family man", had been suffering from depression for a number of years after his younger sister Kelly developed brain damage as a result of her diabetes.
Mr Thomas' mother Sandra described how hard the news had hit her son, adding that the realisation she would no longer be able to speak or respond to him had been "killing him inside".
Mr Thomas also had a mental breakdown in 2011 and was prescribed medication for depression, while the recent death of his grandmother to lung cancer was thought to have affected him very badly.
Toxicology reports on Mr Thomas' body found low levels of alcohol and cocaine evident - the presence of which, Cardiff and the Vale of Glamorgan coroner Thomas Atherton said, combined with his emotional state, probably contributed to his decision to take his own life.
"Given that once on top of the viaduct he would have had to scale a sixfoot high wall in order to jump I'm satisfied that he'd driven there with the intent of doing just that," he said.
"There can be no other explanation."
