He was the only son of the King's eldest daughter, Princess Ubolratana Rajakanya, and her American (former) husband Peter Ladd Jensen.

He spent his childhood in San Diego County, California, where he graduated from Torrey Pines High School.

[6] Jensen drowned after being struck by the Indian Ocean tsunami on 26 December 2004, while he and his family were on holiday at the La Flora Resort hotel in Khao Lak.

His uncle, then-Crown Prince Maha Vajiralongkorn, identified his body and flew the rest of the family to Bangkok.

His mother, Princess Ubolratana, established the Khun Poom Foundation in his memory, to aid children with autism and other learning disabilities.
