Relatives of a Calgary man killed in Thailand earlier this month say they believe money can be the only reason why someone would want to kill the Dale Henry.

Henry, 48, was shot in his Ranong home on Feb. 3. Hours later, police arrested his Thai wife of six years, her lover and an alleged hit man in connection with the killing.

The family says Henry was killed for a $1-million life insurance policy provided by his company, Noble Drilling, to which he had listed his wife, Maneerat Henry, as the beneficiary.

According to Thai authorities, Maneerat waited until her husband had fallen asleep in front of the television and then sent a text message to her Thai lover, who came in through a door that had been left unlocked. They allege that Henry was shot at close range in his bed while he desperately struggled to get away.

"I know he was shot and he put his hands up to block it," Henry's niece Charmaine Von Der Ahe told CTV Calgary. "They found shots through his hand and into his head."

Describing her uncle as a kind man who tried to provide everything he could for his wife and her family, Von Der Ahe says she doesn't know what would lead someone to do something like this other than greed.

"I don't know why she would do it, she got everything she wanted," Von Der Ahe said. "We don't know what else would persuade somebody to do this... I know he loved her very much."

Henry grew up in Victoria, B.C. and worked as a paramedic and firefighter in Alberta for 30 years. He then moved from Calgary to Thailand and fell in love with Maneerat six years ago while working at a bar on Koh Samui. They dated for eight months before getting married.

Henry had been working in Nigeria as regional head of safety for Noble Drilling. Every three months, he would take a month's vacation with his wife in Thailand.

In another development, Henry's sister, Mary-Jane Matheson, said she has gone from sad to angry after hearing that her deceased brother's home was allegedly looted by Maneerat's family.

In an interview with the Canadian Press on Monday, the 46-year-old Calgary resident said she has been told relatives of his wife are looting her brother's Thailand home, and have already taken his cars and motorcycle.

"Her family has been in there," Matheson told CP in an interview. "I phoned his house and his wife's sister answered. They're looting everything he had. His vehicles are gone. There's some man riding around town on his Harley."

Matheson said she was heartbroken to hear of Maneerat's arrest after knowing her brother believed he had found true love. "He just loved this woman with all his heart and trusted her," said Matheson. "His bank account was open to her and he was building a house for her parents and bought four acres of land by some hot springs and all that kind of stuff.

"I'm really hurt that people would do that to him after he had given everything he had and you know he gave her everything.''

Henry's body will remain in a Buddhist temple for three days before cremation, she said. The family chose to keep with local tradition for his funeral because, they say, he loved his adopted culture.

"That's what he believed in and he loved the country and he believed in the morals of that religion,'' Matheson told CP. "He loved animals and treating people well and being kind. He didn't grasp the concept of all the God stuff."

Matheson, who is heading to Thailand for the funeral, said she worries her brother's death may not be pursued diligently in the Thai justice system.

Henry's death marked the second time in less than two months that a Calgarian has been killed in Thailand. Leo Del Pinto was shot in the face and chest in December by an off-duty police officer in northern Thailand. The officer was charged with murder but has no yet gone to trial.
