A wealthy British businessman and his Thai wife were found murdered in shallow graves as part of a hit job ordered by the woman’s estranged brother, according to a report Tuesday.

Alan Hogg, 64, and his wife Nott Suddaen, 61, were killed as a result of a long-running beef harbored by Suddaen’s older brother, Warut Satchakit, the Telegraph reported.

Satchakit hired three hitmen for 50,000 Baht – or just over $1,540 – to rub out the couple at their home in Phrae province in Thailand sometime last week.

“We have found the bodies of the couple, they are buried by the canal,” Thai Police Major General Sanpat Prabpudsa told The Telegraph.

Police said the murders stemmed from a “long-standing conflict within the family.”

“The brother-in-law had problems with money and there were family issues,” Prabpudsa told the Guardian.

The trio of suspects admitted to shooting Hogg near his duck coop on the gated property — then beating Suddaen to death with a hammer.

The couple, reported missing by a pal last Thursday after they didn’t show up to meet friends, was buried in six-foot-deep graves near a creek by the property.

Blood was found smeared in a sink and along the walls of a changing room near their swimming pool.

Satchakit was busted after being caught on surveillance video entering the couple’s property and taking off in their new Ford Ranger pickup truck, which he sold a day after they went missing.

He was charged with theft and released on bail — but has since fled.

Hogg, who was born in Zambia but lived in Edinburgh, married Suddaen in 1986.

Their neighbors in Thailand said she was “the most beautiful woman in town” and said Hogg was “very friendly” and a millionaire.

Last year, Hogg resigned as director of his co-founded professional dry-cleaning company Clayfull, headquartered near Edinburgh.

He also worked as an offshore construction manager and moved to Thailand several years ago after doing engineer work in Australia.

The couple raised ducks, geese and cattle at their home and often traveled Down Under.
