The three-year-old son of a British celebrity stylist has been found dead alongside his German designer father in a suspected murder-suicide in Portugal.

The bodies of Clemens Weisshaar, 44, and son Tasso were located early Sunday morning near the village of Santa Margarida da Serra, in a mountainous area 80 miles south of Lisbon.

Weisshaar was dead from a self-inflicted bullet wound to the head while Tasso’s remains were found inside a burned-out car, police sources have said.

The grim discovery was made a week after mother Phoebe Arnold – a well-known stylist with clients including Paloma Faith – reported the pair missing when Weisshaar failed to return Tasso following a weekend visit.

It is thought the pair had been dead for three days. A post-mortem investigation is underway to establish the exact time of death and the cause of the boy’s death.

Ms Arnold and Weisshaar had been dating since at least 2016, according to social media posts, and are thought to have been married.

The globe-trotting pair had spent time in Portugal together before separating, which happened in July this year according to Portuguese media.

Primary custody of Tasso was awarded to Ms Arnold.

She then moved to Lisbon along with Tasso, while spending time apart from her estranged husband.

Weisshaar, who had an office in the town of Grandola near Lisbon, is then thought to have visited the pair in late October.

Having spent at least several weeks apart from his son, he is understood to have taken custody of the boy with a ‘promise’ to return him by November 1.

Ms Arnold reported the pair missing the same day after Weisshaar failed to reappear.

Police launched a search, before the pair were eventually found close to a plot of land that Weisshaar owned and was building a house on.

Contacted by MailOnline today at her London home, Ms Arnold’s mother said: ‘It’s a very upsetting situation and we don’t want to talk about it.

‘I’m sorry, it’s too distressing.’

British-born Ms Arnold was heavily involved in the world of fashion, having co-founded Ponystep magazine before going on to work as fashion director at magazines including Garage and Elle.

She was also a celebrity stylist who counts singer Paloma Faith among her clients, having worked with her since at least 2018.

The singer credited Ms Arnold with creating her look for the British Vogue fashion awards ceremony in February last year, and during Comic-Con in 2019.

Among her other famous friends were model Lady Eliza Cummings and designer Katie Jan Hillier.

She was also pictured alongside the likes of Gigi Hadid on her Instagram page.

Weisshaar was a famous German designer – born in Munich, he studied in London at Central Saint Martins College of Art and Design and the Royal College of Art.

He founded his first independent design studio in 2000, before going on to create the KRAM/WEISSHAAR studio – based in Stockholm and Munich – in 2002 with American-born partner Reed Kram.

Their work features in the collections of the Museum of Modern Art in New York, the Centre Pompidou in Paris and Fondazione Prada in Milan, among others.
