The family of a Warren County woman who died suddenly last year is suing a paramedic for allegedly failing to provide proper emergency treatment.Jacqueline Jones, 37, whose family resides south of Innsbrook, died in October 2018 after suffering a blocked airway that her family says should have been treatable by a paramedic until she was moved to a hospital.According to a lawsuit filed in Warren County Circuit Court, Jones began having extreme difficulty breathing outside Moser’s Foods in Warrenton on Oct. 25, 2018. She is described as becoming blue in the face and having red respiratory fluid coming from her mouth.Warren County Ambulance District personnel responded to the store just after 10 a.m., and Jones was treated by paramedic Nina Alvarez, the lawsuit states. The suit describes Alvarez trying two unsuccessful methods to open Jones’ airway for almost 10 minutes, before beginning to administer oxygen and preparing her for transport to the hospital.While in transport, Jones’ blood oxygen level allegedly was determined to be dangerously low, 16 minutes after treatment began. Alvarez began assisting Jones’ breathing about 25 minutes into treatment, the lawsuit states.Jones was transferred to the care of St. Joseph Hospital in Lake St. Louis at 10:42 a.m., 38 minutes after treatment began. Hospital staff diagnosed her with a brain injury caused by prolonged lack of oxygen, according to the lawsuit. Jones was transferred to St. Louis University Hospital and died there the next day.The lawsuit states Glenn Craig, then the county coroner, determined the causes of death to be the brain injury and septic pneumonia, a dangerous form of lung infection. Craig reportedly identified “failure to follow medical treatment protocols” as causing or contributing to Jones’ death.Current Coroner Mark O'Neill said the coroner's report from the incident will not be released to the public at this time.Jones’ family also received a professional opinion from an emergency medical doctor in Springfield, Mo., Dr. Charles Sheppard, concurring with the assessment that failure of proper treatment contributed to Jones’ death, according to court documents.The lawsuit was filed in Warren County Circuit Court May 14 by a lawyer representing Jones’ husband, Keith Jones. Her family is seeking unspecified compensation for her death.Todd Hendrickson, the attorney for Keith Jones, declined to provide additional comment on the case. Warren County Ambulance Chief Tim Flake also declined comment pending further review of the lawsuit.The suit is being overseen by Warren County Presiding Circuit Judge Jason Lamb.Court gavel
