In a series of text messages obtained The Blast, Zimmerman called Beyoncé a "broke whore" and promised she and Jay would "find themselves inside a 13 foot gator."
The indirect threats on their lives appear in the upcoming finale of the six-part documentary series.
We're told the messages were sent when Zimmerman was contacted by Dennis Warren, a private investigator who tracked down potential participants for the series. Warren found himself on the receiving end of hundreds of harassing messages and voicemails from the man acquitted in the shooting death of 17-year-old Trayvon Martin.
Back in May, George Zimmerman was charged with stalking and harassing Warren. Just recently, the PI had fought a subpoena by Zimmerman where he demanded to see records of his investigation. Warren refused, arguing that the information on who he contacted could put several already-frightened participants at serious risk.
We're told Zimmerman also sent similar texts to Michael Gasparro, who executive produced the series alongside Jay-Z. Zimmerman messaged Gasparro with the producer's own address and told him members of the Genovese crime family, a powerful organized mafia family, were looking for him.
George Zimmerman's messages to the production crew mirror ones he directed at Jay-Z last fall when he threatened to "beat" him and feed him to an alligator after he claimed production harassed his family for interviews.
"Rest in Power" takes an in-depth look at Trayvon Martin's murder, examining everything from the trial to the judicial system that paved the path for Zimmerman's acquittal to the movement Martin inspired.
The final episode of the six-part docuseries premieres Monday at 10:00 PM ET on the Paramount Network.
