Aarons introduces himself to Hugh Tilles by saying "My name is Charles Aaron." Tilles immediately says "What can I do for you, Mr. Aarons?" and he is referred to as Aarons for the rest of the episode.
A sign at the Dept. of Motor Vehicles reads "Computor Programmers" with the word Computer misspelled.
The key piece of evidence for finding the killer is a computer bank record detailing the transfer of $100,000 to Aaron's account. McGarrett is very reluctant to obtain a warrant for this information. Such warrants are commonplace today.
