Charles D. Englund-Lim, Holly A. Arnold and Cory J. Stone are being held in the Ada County Jail on felony charges of delivery of a controlled substance after Boise police say they drove around and sold heroin to others — with a toddler in their car.

Englund-Lim and Arnold, 23 and 22, also are charged with felony injury to child in connection with the arrest. Boise police arrested the trio after a traffic stop near Maple Grove Road and Emerald Street about 4 p.m. Tuesday. A child under the age of 2 was in the car. Police declared the child to be in imminent danger and placed the child in the custody of the Idaho Department of Health and Welfare.

Police reports do not say why the 26-year-old Stone was not charged with felony injury to child.

Narcotics detectives say they have been investigating the trio since February and they have evidence they sold heroin to others prior to Tuesday’s arrest with the child in the car.

Police officials didn’t release much information on the case. Officers did say they found an undisclosed amount of heroin, packaged for sale, in the car along with other items of drug paraphernalia.

The three people will make their initial court appearances later Wednesday.

The crime of delivery of a controlled substance (heroin) is punishable by up to life in prison. Felony injury to child is punishable by up to 10 years in prison.
