FLORENCE — A 16-year-old San Tan Valley boy will be tried as an adult on kidnapping and armed robbery charges, Pinal County prosecutors have decided.

Samuel Fagan was charged as an adult May 17 with four felony counts. He is accused of kidnapping, armed robbery, aggravated robbery and aggravated assault.

According to court documents, Fagan is accused of kidnapping and restraining a man on March 2 in San Tan Valley “with the intent to inflict death or physical injury.”

Court records indicated that Fagan also used a firearm in an alleged attempt to rob and assault the man with at least one unnamed accomplice.

Though the alleged kidnapping and robbery occurred in March, Fagan was not charged as an adult until May. There is evidence of a previous juvenile case filed against Fagan in Pinal County Superior Court.

According to paperwork in the court file, on June 6 Fagan made an initial appearance before an unnamed juvenile judge in Superior Court, was in the custody of the Pinal County Juvenile Detention Center and was represented by Pinal County public defender Gail Matheny.

Matheny said the client did not want to waive his rights to a preliminary hearing and requested the matter be set for a preliminary hearing to establish probable cause.

The matter was set for preliminary hearing before Judge Lawrence Wharton at 4 p.m. Friday but it was canceled. Fagan was remanded to the custody of the Pinal County Adult Detention Center but ordered to “be held out of sight and sound of the adult population.”

Fagan is being held on $50,000 bond, ordered by Pinal County Superior Court Judge Kevin White on Monday.

Fagan is scheduled to appear back in court at 9 a.m. on July 22.
