OLMOS PARK, Texas — Surveillance videos, witness accounts and cell phone records are just some of things investigators used to track down Brad Simpson’s whereabouts after his wife, Suzanne Simpson, disappeared on Oct. 6.
Those details are outlined in a nine-page affidavit, filled out by an Olmos Park Police lieutenant, that alleges Simpson is responsible for his wife’s death. He was arrested on Oct. 9 on family violence charges and was charged with murder on Nov. 7, while still in custody.
A murder arrest affidavit released Tuesday shows how investigators pieced together a timeline of his whereabouts and how they believe his actions point to guilt.
