When Mace saw Jina lying in the sand, he knew she had been aware that she didn't have
much time left. So if you wanted help, why not shout out for help? What good does it do to
write it in the sand? Wouldn't she much rather finger the person who did this to her? Mace
thought so, and so realized that she had not written "help" in the sand, she had written
"Shelby" to finger her killer. However since they found her a bit late, some of the letters had
washed away with the waves. Shelby killed her in a fit of rage, when she found out he was
stealing money from his own employees at the club.
