The Mesa County Sheriff's Office is looking for anyone who may have seen a family van that may have been used in the disappearance of Abby and Jennifer Blagg.

The van (pictured, left) was found in the garage of the Blagg home the day the two disappeared and has been in the custody of the sheriff's office since then.

Officials believe Abby and Jennifer may have been removed from their residence in the van.

Wednesday, the sheriff's office released a photo of the van in a flyer that asked "Did You See This Van?"

The sheriff's office asked that anyone who has information concerning the van either coming or going from the Blagg residence at 2253 Pine Terrace Court between 8 p.m. Nov. 12, 2001, and 4:30 p.m. Nov. 13, 2001, or who has seen this vehicle in a remote or semi-remote area of Mesa County to please contact the Mesa County Sheriff's Office at (970) 244-3500 or anonymously contact Crime Stoppers at (970) 241-STOP.

On Nov. 13, Michael Blagg reported that he found a pool of blood on Jennifer's bed and both his wife and daughter missing. The family van was still in the garage.

Authorities have said they don't believe a stranger is responsible for the mother and daughter's disappearances .

Sheriff's investigators have traveled to Arizona, California, South Carolina, and Texas to interview the Blaggs' former neighbors, friends, and relatives in connection with the missing persons case.
