A second person has died following a water buffalo attack at a farm in Monmouthshire.
The 19-year-old is believed to be Peter Jump, the son of Ralph Jump, who was killed in the incident on 5 May.
A spokesperson for Gwent Police said: "A 19-year-old man was taken to the University Hospital for Wales by the Welsh Air Ambulance after sustaining critical injuries."
On Wednesday, police confirmed the teenager died in hospital as a result of his injuries on 6 May.
They added an investigation has been launched which remains ongoing.
A 22-year-old woman from the Gwehelog area also sustained a serious injury to her leg. She received hospital treatment for her injuries, which are not thought to be critical.
In a tribute, Ralph's brother Richard said he had lost his "best friend" and "wonderful nephew" and described the loss as "surreal and insurmountable".
Police confirmed the water buffalo was put down.
One neighbour said: "One of the buffalo managed to escape its pen and it attacked when they were trying to get it back in. It's an absolute tragedy."
The family had begun making hand-made soap products using buffalo milk.
An inquest is due to be held by the Gwent coroner at a later date.
