The mother of a B.C. man suspected of abducting a three-year-old boy is pleading for him to turn himself in.

Randall Hopley, 46, is wanted in the disappearance of Kienan Hebert, who was last seen by his parents on Tuesday night at his Sparwood home.

A province-wide Amber Alert issued two days ago and a manhunt involving hundreds of volunteers have turned up no signs of the boy.

Speaking to CTV News from her home in Fernie, Margaret Fink, 70, said she hasn't been well since hearing that the police believe her son abducted a young child.

"My heart hasn't been good," she said. "I was just shocked – so shocked."

"I would like for him to come home safe and the little boy to come home. I couldn't sleep last night worrying about what the hell they were doing."

Fink said her son paid her a surprise visit on Tuesday, the day Hebert disappeared.

Randall, whom Fink calls "Randy," arrived to his mother's home freshly shaven and armed with new car insurance for his 1987 Toyota Camry. It was the first time she'd seen him in a year.

"When he come in right away he was biting his nails but he seemed to be alright. He said he did some helping painting and taking a roof apart, that's all he said," Fink said.

Fink, who has heart problems and needs an oxygen tank to breathe, says her son needs to turn himself in.

"I hope that Randy will listen to me or come home. And I hope the little boy is safe and sound and we all wish him well," she said.

Fink also had a message for the Hebert family: "I would like to say I'm sorry if Randy has him."

Hopley grew up in Fernie -- one of five siblings. He was just six years old when his father died in a mine blast.

Fink said her son started getting into trouble and wound up in several foster homes throughout his childhood.

"They took him out of the school … because I wasn't married and he was kicking up trouble. Then they sent him to Vancouver," she said.

Hopley has an extensive criminal record, including a conviction for sexual assault.

He was charged with the abduction of a child and unlawful confinement in 2008, but those charges were later dropped.

Fink believes her son may not be far away.

"With him he likes Sparwood. That's his favourite place. As long as the car gets up the trail, he's up in those trails."

Anyone with information about the disappearance is asked to call 911 immediately.
