FARMINGTON — The San Juan County Sheriff's Office said a 67-year-old woman was robbed at gunpoint after she offered one of her attackers a ride home.

The sheriff's office said they are seeking information about a man and woman who may have been involved, according to a news release.

Detective Lt. Cory Tanner said the victim was the Walmart on East Main Street in Farmington at about 10 p.m. Wednesday when a woman in her 20s or 30s asked for a ride home.

The woman agreed to give the suspect a ride and drove south on N.M. 371 about 4 miles south of Farmington city limits when her passenger asked to stop to use the rest room.

"Upon pulling off the road the victim noticed another vehicle pull up behind her," Tanner said in a statement. "The female suspect pulled out a pistol and began beating the victim with the butt of the pistol."

Tanner said a man got out of the second vehicle and also beat the woman.

Police said the woman tried to get out of her vehicle but couldn't.

The robbers stole the woman's purse, cell phone and keys and fled, according to the release.

The woman signaled for help. She was taken to San Juan Regional Medical Center where she was treated for non-life threatening injuries, according to the sheriff's office.

The suspects are described in the news release as being a Native American man and woman in their 20s or 30s.
