When Justin Lamar Sternad met Ana Sol Alliegro at a Miller’s Miami Falls Ale House, he didn’t know the political consultant would help lead his campaign into the FBI’s crosshairs or that she had prior legal run-ins — including the time she shot at her ex-husband while naked.

Alliegro is a key figure in a federal investigation of Sternad’s campaign finances that focuses on the funneling of tens of thousands in cash tied to U.S. Rep. David Rivera.

Authorities believe Rivera and Alliegro, both Republicans, helped the Democratic Sternad undermine a political rival in his recent congressional primary race.

“Politics is rough and I play like it,” Alliegro, 42, once tweeted on Twitter.

Now she’s missing or has been in hiding for the past two weeks, according to her family and lawyer, who said they’re “worried” about her.

A self-described “Republican bad girl,” Alliegro doesn’t appear to be cooperating with authorities investigating Sternad’s campaign. The political newcomer and part-time hotel worker lost the Aug. 14 Democratic primary race to Rivera rival Joe Garcia, who faces Rivera in the Nov. 6 general election for the Kendall-to-Key West seat.

Alliegro initially planned to cooperate with the FBI and make a statement on Thursday, Sept. 6. But she was a no-show.

The day before, she met with Rivera, who faces a separate criminal investigation into his personal and political finances.

The investigation into Sternad’s campaign concerns laws prohibiting money laundering, intentionally filing false campaign reports and conspiracy. No charges have been filed against Sternad, Alliegro or Rivera.

And it’s not the first time Alliegro has faced legal problems.

Two weeks ago, right after FBI agents raided her apartment and seized her computer, Miami Police arrested her on an old warrant for driving with a suspended license. She spent the weekend in jail, where she complained about the smell and view from her cell.

In 2009, she was arrested for shoplifting a pair of $29.99 sandals from Ross on Biscayne Boulevard. The charge was later dropped.

In January 2007, she was arrested in a dispute with her ex-husband, Moshe Cosicher, at his Tigertail Ave. home in Coconut Grove. They had been divorced for two years, but Alliegro wanted to get remarried, according to reports from Miami police and prosecutors.

“We are going to Vegas,” she told Cosicher, a report said. The report noted that when Cosicher refused, she grabbed a gun, which appeared to be a .45 that she kept at bed side.

She then sat naked at a desk with her leg up and compared the gun to a male sexual organ.

“If you think your [expletive] is powerful (showing the gun), this is mine,” Alliegro told Cosicher, who tried to ignore her by going to make coffee, a report said. Alliegro followed him and told him to sit on the couch.

She fired a round into the ceiling.

“You see. It’s loaded — this is business,” Alliegro allegedly said. He tried to leave.

“She shot at me when I approached the front door (she missed my head by inches),” Cosicher wrote in a police statement. He said he was able to defuse the situation when a contractor, who was performing work for him, happened to call and then stop by.

Cosicher, an architect who had first met Alliegro when she was a secretary years before, gave the statement later in the day, in part because he feared for his family after Alliegro allegedly said “she hated herself and her life and had nothing to lose by taking me and my entire family down with her.”
