FARMINGTON — Police are trying to find out what role two women had in the armed robbery of a Farmington family last week.

Alton King, 41, was arrested last week after police said he forced his way into a family's home in Farmington, stole a computer and pointed a gun at a mother and her young son before leaving while shooting bullets into the air, Farmington police Lt. Taft Tracy said in a news release.

King has been charged with armed robbery, aggravated burglary, shooting from a motor vehicle, child abuse, aggravated assault, possession of a firearm by a felon and other crimes, according to court documents.

Two women who allegedly may have assisted King in the robbery have not been charged.

Before King rushed into the home, on Melba Lane in Farmington, a woman knocked on the door and the mother answered.

After a brief exchange, King forced his way inside the home and pointed a gun at the woman and her 9-year-old son. King repeatedly asked the woman where her boyfriend was and then took the computer and handed it to another woman who came to the front door.

Police believe that woman was Tiffany McCants, King's sister, according to court documents.

Tiffany McCants and King are Diane McCants' children. Diane McCants is the chairwoman of the San Juan County Democratic Party.

Reached by phone Monday, McCants said they were her children but declined further comment.

Police said King and Tiffany McCants were driving a 2002 GMC truck registered to Diane McCants the night of the robbery.

Tiffany McCants has not been charged with a crime.

"The investigation into her involvement in the crime is ongoing," Farmington police Det. Robert Perez said.

King has three felony convictions in San Juan County dating back to 2002 for robbery, false imprisonment and felony DWI.

He is being held at the San Juan County jail on a $175,600 bond.

Anyone with information about the incident is asked to call Farmington police Det. Paul Gonzales or Perez at 505-599-1005 or San Juan County Crime Stoppers at 505-334-8477.
