MIAMI (CBSMiami) – Three notebooks belonging to a Hialeah woman accused of ballot fraud have been entered into evidence in her case.

The books, found in the possession of accused ballot broker, or boletera, Deisy Penton de Cabrera, reportedly contain meticulous notes on several political campaigns which she allegedly received payments from between 2008 and 2012, according to CBS4 news partner The Miami Herald.  Cabrera was arrested in August 2012.

The notes, which include remarks on hundreds of voters, allegedly detail payments of $50 to $1, 300 which do not show up on the books of the listed campaigns.

Cabrera, 57, reportedly jotted down the information last summer and used abbreviations that are difficult to decipher.

According to the paper, Cabrera had names and addresses of more than 500 voters who were mostly elderly Hispanics who live in Hialeah. The lists, titled “Deisy’s Voters,” reportedly included information as to whether the voter was illiterate or was blind, deaf or had Alzheimer’s.

In 2008, she allegedly received more than $9,000 in payments from more than half a dozen judicial candidates. Cabrera worked as a campaign worker for three of the candidates but what they paid her was about half of what she listed in her notes, according to the paper.

Investigators say Cabrera didn’t work alone. She reportedly was a part of a political apparatus with access to updated absentee voter information from Miami-Dade County’s Election Department and kept directives written by others to visit particular groups of voters or to take others to early-voting polling places.

She also kept contact information for the campaigns for which she worked, including those of former U.S. Rep. Lincoln Diaz-Balart and state Sen. Rene García.

Cabrera allegedly began to work with voters months before Election Day. Some of the ballot request forms were filled out in her handwriting, according to the paper. Others were pre-printed with the voter information. They were dated seven months before Hialeah’s municipal elections.

Friends described Cabrera as a “poor soul” who lives in a Section 8 apartment and has health problems, according to the paper.

Cabrera has been charged with one felony count of ballot fraud and two misdemeanor counts for allegedly violating a county ordinance that prohibits the collection of absentee ballots.

She has entered a not guilty plea.
