The couple鈥檚 son, Simeon Garratt, says he has no idea why his parents have been detained after living in the country for so long.
"My only assumption is that there was some sort of misinformation along the way," Garratt tells 麻豆影视 from Vancouver. "It's just an absurdly crazy story. It just makes no sense to me at all."
The couple is Christian, and China has been cracking down on religions and demolishing Christian churches, but Garratt doesn鈥檛 think that鈥檚 the reason for their detention.
"It's never been a secret that they've been Christian," he says. "There's nothing that has happened in the last week or so that would have changed the situation."

After two days of silence, the couple is able to send a message to their son, saying they are not under physical duress but are confused and upset about the allegations.
"They just wanted everybody to know that they're safe," Simeon Garratt tells The Canadian Press.
"Physically they're fine, but they're really, at this point, just very frustrated and confused and are just hoping that the Chinese government is able to see the truth."
