The RCMP in Brooks, Alta., have charged a 30-year-old man with second-degree murder in connection with the death last month of 17-year-old Ashton Moen.

Colin George Winsor was arrested on Thursday. Police claim he was known to Moen and may have given her a ride to work on June 19, the last day she was seen alive.

Immediately after her disappearance, police said they were investigating a missing persons case.The search for Moen was scaled back after less than a week because of information that she was living in Calgary.

On Canada Day, a man walking his dog found Moen's body beside an irrigation canal just outside of the town of Brooks.

A murder investigation was launched and everyone who had spoken to police during the missing persons case was reinterviewed.

At a news conference in Brooks Friday, police said that Moen was killed the same day that she disappeared.

Ashton's father, Ronan Moen,saidhis family is relieved there has been an arrest, but it doesn't bring his daughter back.

"We're grateful to theRCMP for their quick response, we're grateful to the community as well for the great support that they've provided and also to the media for the help they've provided in the stories, as well as accepting our privacy when we asked for our time of mourning," he said.
