Jamison was a contractor and owner of Jamison Contracting.
Jamison went to a home improvement center and hired Eduardo Salcido and Manuel Ruiz to work. However, Manuel had an accident and died after falling from a roof. Not wanting to have his permit revoked or the job halted, Jamison convinced Eduardo that Manuel's death had been his fault and since he was illegal, he shouldn't say anything. He later had Eduardo buried on the grounds he was working in.
When Detectives Dutch Wagenbach and Claudette Wyms came by his work asking for Manuel Ruiz, he denied knowing where he was. Dutch and Claudette did find Eduardo Salcido, who confessed about Manuel's death. Claudette and Dutch then went back to Jamison's company and found Manuel's body buried there. When Jamison saw what was happening, they had him arrested.
