“According to the complaint, Brumfield purchased a 2003 Saturn Ion on Feb. 28 from King Auto Sales in Cahokia. A few weeks later at 8:30 a.m. on March 11, Brumfield alleges police officers responded to a wellness check when the Ion was parked on Lincoln Ave. in St. Louis. First responders allegedly arrived on scene to find the Ion running idle with Brumfield and her three minor children unresponsive in the vehicle.”
