Inscriptions of Rix's limerix

At the Costco book signings, the author of Jingle Jangle plans to inscribe a limerix appropriate to the apparent interest of each purchaser:

The foibles of the jury?

Cop says he killed her
Bitemark experts concur
    Defense creates doubt
    Jury can't figure it out
Sends Ray Krone to stir

Rix's own role as a contemporary Sherlock Holmes?

Cops catch a snaggletooth
I become a sleuth
    Cops claim he bit
    Evidence doesn't fit
I'm amazed at the truth

The immediate efficacy of DNA in winning his cousin's release?

Evidence a bite mark
Experts to jury bark
    DNA
    Saves the Day
Bite mark analysis a lark

Jingle Jangle as a whodunit?

Cousin Ray did the time
Who did the crime?
    Read ‘tween the lines
    Discover the signs
Solve this riddled rhyme

Other suspects?

The story of the Snaggletooth Killer
Is a real whodunit thriller
    But was it Ray
    Or two women gay
Or the man doing time in the chiller?
