After the accident Booker told CBS4 that he didn’t remember the accident because he suffered from a seizure.

According to the arrest affidavit Booker lied on multiple accounts about his medical condition in order to get his driver’s license and shouldn’t have been driving.

Officers said the investigation took a long time because they had to search through many medical and DMV records.
