A Royalton mother is still looking for answers, after her son remains missing for more than a month.

"It is like he vanished in thin air," said Deaunna Mckinne. "No signs of what happened. Just really scary because you don't know."

Austin Colson, 20, disappeared January 11 and has not been seen since.

His mother spends most of her days waiting by the phone and fearing the worst.

"For a few weeks now I have been feeling that way," said Mckinne. "That is he no longer with us."

Police say Colson planned to sell scrap metal on the morning he went missing. A few days later, a trailer that he borrowed from his dad was found filled with metal on a back road in Sharon.

"It is really hard. I have a lot of days where I am upset and I just sit there and cry," said Mckinne. "It is really hard to process something like this, especially when you don't know what happened."

Police are still trying to figure out what happened, but say there is a suspect in Colson's disappearance.

As of Monday, Richard Whitcomb, of White River Junction, was being held on an unrelated gun possession charge.

Whitcomb allegedly told police that he used a gun as collateral during a drug deal with Colson.

According to family, he was the person Colson was meeting with the scrap metal.

Mckinne has known Whitcomb for years.

"I'm shocked. I didn't think he would do something like that, if he is the one. He should man up to it. If they have got evidence now, there is no use in hiding," she said.

Mckinne also says other people likely know more than they are saying.

"I'm sure that there is some people out there that do know what happened to my son that day that are keeping quiet," said Mckinne.

Mckinne says any new information could help crack the case, even if it's an anonymous tip.

Austin's father says he is pleading with every homeowner in the Upper Valley to check their yards to make sure there is no sign of his son.
