Reid told officers he had two to three drinks and was on an Adderall prescription at the time of the incident, FOX 4 Kansas City previously reported, citing police documents.

Police said the investigation into the crash will take at least a month, the station reported. Results from blood tests to determine whether Reid was impaired were expected to take about four to six weeks.
