POCATELLO, Idaho (AP) - Two Pocatello residents have been arrested after a counterfeit printing bust netted drugs and a knife believed to have been used in a stabbing last month, police said.

Christopher Keeling, 20, and Shannon Esterholdt, 29, were booked into the Bannock County Jail without bond pending a court hearing scheduled for Monday.

Both have been charged with felony forgery by possession of counterfeit notes, felony possession of methamphetamine and injury to a child.

Keeling was a person of interest in a stabbing Feb. 11, but charges were not filed because officers hadn't found the weapon.

With the knife's discovery Thursday, he's also been charged with aggravated assault with a knife.

Police began investigating a possible counterfeit operation after reports that fake bills were being used at local businesses. They were led to a home where Keeling and Esterholdt were staying, and found the knife, more fake bills and drug paraphernalia on the floor, including a syringe containing meth residue.

Police found several counterfeit bills in various stages of production and a computer and printer believed to have been used to alter one dollar bills into phony 10 and 20 dollar bills, the Idaho State Journal reported Saturday.

Two children under age 10 were also in the home which officers said was filthy and smelled of rotting food. The children were placed in the custody of the Department of Health and Welfare before being released to their grandparents.

The children's relationship to Esterholdt or Keeling was not immediately clear, and police reached by The Associated Press on Saturday did not know.
