(The Blaze/AP) -- The former neighborhood watch volunteer who killed Trayvon Martin told his wife to buy bulletproof vests for them and for his attorney, according to jailhouse calls released Monday. But they also reveal the couple may have been hiding how much money they had on hand.
"As uncomfortable as it is, I want you wearing one," George Zimmerman told his wife. Zimmerman was wearing a bulletproof vest when he left jail after posting bond. His attorney, Mark O'Mara, has reported receiving threats.
The calls, released by prosecutors, also detail how Zimmerman instructed his wife to transfer money from bank accounts and could play a crucial role in his second bond hearing next week.
Zimmerman was released on $150,000 bond in April, several days after the calls took place. At his bond hearing, his wife, Shellie, testified that she didn't know how much money had been raised from a website created for his legal defense. She also testified that they had limited funds because she was in school full time and Zimmerman wasn't working.
Prosecutors say the calls show George and Shellie Zimmerman knew that roughly $135,000 had been raised by the site.
Watch Fox's explanation of the problem:
Shellie Zimmerman was arrested last week on a charge of making a false statement. George Zimmerman is charged with second-degree murder. He has pleaded not guilty, claiming self-defense during the confrontation with the 17-year-old teen in a gated community in Sanford, Fla. The case sparked protests across the country when George Zimmerman wasn't arrested at first and led to nationwide debate over race and self-defense laws.
In one call, Zimmerman tells his wife and sister how to change a computer password at a credit union so they can move funds around. They also seemingly tried to speak in code about PayPal, using the words "Peter Pan" repeatedly.
In another call, Shellie Zimmerman said that money raised from the website was also being used to pay off bills. The couple also talked about how they would whisk Zimmerman away from the Seminole County Jail once he was released in April, and discussed using a rental car to drive to a hotel parking garage. There, they would change into another rental car to throw off anybody who tried to follow him.
Shellie Zimmerman told her husband that the website had crashed because of supporters leaving words of support, as well as donations. They also talked about the life that awaited them once everything was over.
"After all this is over, you're going to be able to have a great life," she told him, according to the Orlando Sentinel.
"[We] will," he corrected her.
"Yeah, we will."
Prosecutors originally had planned to release 151 of Zimmerman's jailhouse calls, but O'Mara objected. A hearing over their release is set at the same time as Zimmerman's bond hearing next week.

"It is our contention that the calls are not only irrelevant to the charges against Mr. Zimmerman, but they could jeopardize friends and family of Mr. Zimmerman who are unrelated to the case," O'Mara said on a website for Zimmerman's legal defense.
