FBI checks envelopes used in probe of Rep. David Rivera

A key witness in a federal grand jury case involving U.S. Rep.David Rivera is still missing, but she left important evidence behind for investigators: at least four envelopes that had been stuffed with unreported campaign cash.

Ana Alliegro, a Republican political operative, delivered the cash-stuffed envelopes to a Hialeah mail house that sent out fliers in a congressional race against a Rivera political rival, the mail house owner told the FBI.

The FBI has the envelopes to check for fingerprints and handwriting comparisons.

Also in the hands of FBI agents: at least six invoices initially made out to the attention of David Rivera — all marked paid “cash” — to cover the mailings for Democratic primary challenger Justin Lamar Sternad, a suspected Rivera straw-man candidate. The congressman demanded that his name be removed from the invoices with Wite-Out, documents and interviews show.

Alliegro went missing two weeks ago, shortly after her computer was seized by FBI agents and just hours before she was scheduled to talk to a federal prosecutor about her involvement in the Rivera-Sternad operation. She also had been jailed by Miami cops on an old suspended driver-license warrant.

“Am I worried? Yes,” Mauricio Padilla, her lawyer, said Friday. “I have not heard or seen her. This has never happened to me before.”

Enrique “Rick” Yabor, who represents Sternad, said he and his client would not comment.

Sternad initially failed to report the cash receipts or expenditures — totaling at least $47,000 — which could violate federal campaign laws concerning financial disclosures for congressional candidates. It’s also illegal to conspire to break federal laws and launder money.

Rivera, already under a separate federal criminal investigation into his personal and campaign finances, denied any association with Sternad, who often attacked candidate Joe Garcia in the Aug. 14 Democratic primary.

Garcia won that race and now faces Rivera in the general election for the Kendall-to-Key West District 26 seat.

Rivera did not return two calls to his cellphone Friday night, and his campaign aide Javier Correoso, did not return a call or email for comment.

Republican Mitt Romney’s presidential campaign has kept its distance from the congressman. Rivera is the only one of Miami’s three Republican congressmen who has been consistently absent from Romney campaign events, such as a Univision forum in Coral Gables and a Miami rally on Thursday. Until recently Rivera had been publicly stumping for Romney, even rallying listeners on Spanish radio to join him in supporting Romney.

Meanwhile, the Democratic Congressional Campaign Committee has reserved about $1.5 million worth of air time, starting in mid October, for the Miami-Fort Lauderdale media market. A good portion of that money — though not all — is likely to be spent on the Rivera-Garcia race. In contrast, the Republican committee plans to spend nothing on Rivera.

The two faced each other in a bitter 2010 race that Rivera won in a landslide.

Garcia decided to run again this election. He faced three other Democratic candidates, including Sternad. The Garcia campaign began accusing Sternad of acting as a stand-in for Rivera and noted that the fellow Democrat, an unknown political newcomer, was using a Hialeah company that Rivera had used for years, Rapid Mail & Computer Services.

In all, Sternad sent 12 mailers in the race — one of which savaged Garcia over his divorce by using a line of attack that originated with Rivera.

The owner of Rapid Mail, John Borrero, first told The Herald in early August that he had been paid in cash — a rarity in campaigns, which usually rely on checks so that a candidate can clearly show the source and amounts of his receipts and expenses. Borrero said that Alliegro paid for the mailers multiple times. All but $9,000 of the nearly $47,000 in work was paid in cash

In August, Borrero said that he turned over two of the envelopes that were in his trash can to Miami-Dade public corruption investigators. They turned the documents over to the FBI, when it opened an inquiry. Agents now have two more envelopes.

Sternad’s primary reports initially gave no indication that he could afford a dozen mailers.

The invoices were initially printed to the attention of Rivera for six Sternad mailers, ranging from fliers titled “Obamacare/Trayvon” to “Lamar for Congress,” records and interviews show. But Rivera demanded that his name be removed, so the invoices only read: “Lamar Sternad for Congress.”

Sternad’s initial reports showed he had loaned himself $11,262, most of which was spent on the state fee to qualify for the Democratic primary ballot. After repeated questions from The Herald, Sternad amended his financial disclosures to show he had loaned himself nearly $53,000 more than originally reported. Still, his reports never showed how he paid for the actual printing of the dozen mailers, which would cost tens of thousands of dollars more.

Sternad’s personal financial disclosures show he is a a part-time South Beach hotel worker who earned just $30,000 last year; he listed a one-third interest in a mutual fund valued at a maximum of $100,000. He derived no income from it last year, his disclosures show.

Sternad’s finances weren’t the only mystery — so was the level of sophistication of his mailers, which targeted slices of the electorate with specialized messages. They were good enough to earn him 11 percent of the vote.

Alliegro took credit for much of the work. FBI agents want to know exactly what she knew and when.

Alliegro’s mother, Agueda “Guedy” Alliegro, said Friday afternoon that she has not heard from her daughter in two weeks and neither have other family members.

“I am worried,” she said. “I know she is resting. We are praying for her.”

Guedy Alliegro said that law enforcement has not contacted her family, which hasn’t filed a missing-person’s report. She said she has no reason to think that her daughter would be cooperating with the FBI.

“Ana has done nothing wrong,” the mother said.
