BUNKER HILL, Kan. (AP) — Russell County authorities say a Kansas woman is in jail after three of her four foster children tested positive for marijuana.

The 54-year-old woman from Bunker Hill was arrested Thursday and jailed on drug charges and three counts of aggravated child endangerment.

Russell County Sheriff John Fletcher says deputies were called to the Russell County Courthouse June 5 while a social worker and state officials were investigating because the woman and her three girls tested positive for the drug.

Fletcher says one of the children told the social worker that the woman and girls also drank milk mixed with bleach.

KWCH-TV reports  the four children were placed in new foster home. Their ages were not released.
