The sister of the accused "Craigslist Killer" says she's lying and stealing her story from a TV show.

Miranda Barbour is charged with killing a man she met through Craigslist and claims to have killed dozens more.

Those claims have not yet been confirmed.

Now the Daily Item of Sunbury reports Barbour's sister says she's a "master at lying" who's drawing inspiration from the TV show "Dexter," which is about a serial killer.

Barbour appeared in a central Pennsylvania court for a pretrial hearing Tuesday.

She is pleading not guilty to the charge.
