A misdemeanor stalking case involving George Zimmerman and a private investigator who worked on the docuseries Rest in Power: The Trayvon Martin Story was back in a Florida court on Tuesday, NBC’s WESH 2 reports.

Investigator Dennis Warren says Zimmerman was stalking and sending him threatening messages, including an article in which he’s quoted as saying “anyone who f**ks with my family will be fed to an alligator,” according to WESH 2.

According to the Blast, Warren says Zimmerman called him 55 times, left 36 voicemails, texted him 67 times and sent 27 email over nine days.

Zimmerman subpoenaed documents related to the investigation involving him to be submitted in a deposition.

Warren objected, saying that the witnesses he spoke with would be in danger if their identities were revealed.

“There are several people out there that are very concerned about their safety,” Warren said in court on Tuesday.

Zimmerman’s attorney shut down Warren’s argument, saying that he was working as a private citizen.

“He wasn’t in the capacity of a law enforcement officer. He was a private citizen working for a private corporation, making a movie for profit, and we’re entitled to know how he came to get this job and what were the parameters of his employment,” his lawyer said.

In 2013, Zimmerman was found not guilty of second-degree murder in the 2012 shooting death of Trayvon Martin, a Black Sanford, Florida teen.

His acquittal caused massive outrage across the country that led to protests and calls from activists for a fair justice system.

The judge said documents in the case could be viewed as objectionable, WESH 2 reports.
