SANFORD, Fla. -

Jailhouse calls show how the former neighborhood watch leader charged with killing Trayvon Martin instructed his wife to transfer money from bank accounts.

The calls released by prosecutors Monday could play a crucial role in George Zimmerman's 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.

Prosecutors say the calls show George and Shellie Zimmerman knew that roughly $135,000 had been raised by the site.

Officials on Friday originally said all 151 jail house calls made by Zimmerman would be released, but Zimmerman's attorney Mark O'Mara filed a motion objecting the release of the jail calls not mentioned in the state's motion to revoke bond.

Zimmerman's defense team also announced on Friday that it had received a a second round of evidence from state prosecutors. According to the website, the discovery package includes seven compact discs and hundreds of pages of documents.  The website says it includes surveillance video, police radio transmissions, crime scene photos, 911 calls Zimmerman made prior to the night of the shooting and more.

The evidence also includes cellphone records of Martin's father and emails from former Sanford Police Chief Bill Lee.

The document issued by court officials says Judge Kenneth Lester issued the discovery to O'Mara and his legal team on Thursday. On O'Mara's website, GZLegalCase.com, the June 1 ruling of the court says the defense will have 30 days to review the discovery before it is made available to the public.

"The discovery process is ongoing, and we expect additional discovery to be disclosed as the case develops," O'Mara wrote.

Zimmerman is charged with second-degree murder in the death of Martin, who was shot and killed Feb. 26.  Zimmerman has pleaded not guilty, claiming self-defense.

His wife, Shellie Zimmerman, was recently arrested on perjury charges after prosecutors said she lied about their finances at her husband's first bond hearing. She has since been released on bond.

George Zimmerman's second bond hearing is scheduled for June 29.
