L/Cpl Jonathan Gouldsmith taxi death witness appeal

L/Cpl Gouldsmith had hopes of being an Olympic skier, said his family

Police have made a further appeal for witnesses after a soldier was killed in a collision with a taxi.

L/Cpl Jonathan Gouldsmith, of the Royal Electrical and Mechanical Engineers, was home on a week's leave when the incident happened on 3 April.

The 24-year-old, from Haverfordwest, Pembrokeshire, was killed in Llanelli after a night out in Swansea.

More than 400 mourners paid their final respects at his funeral at St Davids Cathedral on Thursday.

L/Cpl Gouldsmith had previously completed six months in Afghanistan.

A police investigation into his death continues.

In their latest appeal, Dyfed-Powys Police said they wanted to speak to a female taxi driver and two women who were with L/Cpl Gouldsmith shortly before he died.

Police said that before the incident, L/Cpl Gouldsmith and a friend were driven from Swansea, where they had been on a night out, to Llanelli.

The two men shared the taxi with two women, but the women were not involved in the collision.

L/Cpl was a talented sportsman and was celebrating a services skiing championship win on the night he died.

Six pall bearers carried his coffin into the 1,500-year-old cathedral chapel in St Davids.

Christopher Gouldsmith, his identical twin brother and also a lance corporal with 21 Engineer Regiment, paid tribute.

"More than just a brother, he was a best friend. From when we were young we were inseparable," he said.

"From having our own way of talking to each other, as if it was in code or in a different language, we would understand each other perfectly. We would rarely argue."

He added: "From joining the Army at the same time, and being split up, was the hardest thing of my life - until today."
