The B.C. RCMP's Serious Crimes Unit has created a re-enactment video of the day Abigail Andrews was last seen in a northeastern B.C. city more than three years ago, in the hopes that that new information will come in about her disappearance.

The then-28-year-old woman was a glowing, expectant mother, when she went missing on April 7, 2010, in Fort St. John, police say.

Her father, Doug Andrews, said it was out-of-character for his daughter to lose touch. In the video released by RCMP today, he said his daughter was looking forward to the birth of her child. She was three months pregnant at the time.

"She had pampers that she was stockpiling. She was stockpiling food, all kinds of garments and goodies, in preparation for the birth of this child. She was really excited about it, as were we," he said.

The narrated re-enactment video shows an actor portraying Abigail Andrews walking away from her home. Andrews reportedly mentioned to a neighbour that she was on her way to visit a male friend.

RCMP "E" Division Serious Crime Unit Cpl. Bill Robinson said investigators are pursing the case as a case of foul play.

"Our investigation to-date has resulted in the identification of a suspect. We believe that this person has spoken to people about what they did," he said. "We're asking those people to contact us, no matter how small or how unimportant they feel their information is."

Robinson said that this fall, Andrews' child would have been three years old.
