CINCINNATI (AP) -- An Indiana couple has been arrested in Ohio on child endangering charges because police say they overdosed on heroin in a McDonald's play area. Hamilton County court records show that the fire department in Green Township, just west of Cincinnati, responded to a call Sunday of two adults needing attention in the restaurant's children's play area. Authorities say one was unconscious and not breathing; the other was conscious but unresponsive. They recovered from what police say were "life-threatening overdoses" of heroin. Authorities say the couple acknowledged taking the drugs while with their two children, a 5-year-old girl and 8-year-old boy. Court documents show each pleaded not guilty. Robert Paul Palmer, 37, was being held Thursday on $10,000 bond. Tamica Lynn Jeffers, 33, was being held on $6,000 bond.
