The story of the couple of married assassins, Malcolm and Sandra Boatwright, in the McAllister's first episode, is similar at history of Timothy Carter, the Red John impersonator, and his wife Sally, in Strawberries and Cream/Scarlet Ribbons/Little Red Book. 
In Red John's Friends, Jared Renfrew
draw in the wall, before his death and with blood, the write: He is
Mar... That could be He is MacAllister, or not "He is Mar" but an
incomplete anagram as "l l c is mar...te", then "McAllister". Jared
could prepared this anagram when he was in prison; if Red John will kill
him, the killer would not have deleted the clue.

In Van Pelt file in Red Dawn (even if it is anachronistic, because it happened a few years after) there's the plot of part of McAllister episode, with the "redhead girls killer".
