FORT MYERS, Fla.- New details have been released in the disturbing murder of an Estero grandmother last year. Two men are accused of killing Mary Ann Zarb and dumping her body in the woods. Detectives interviewed more than 55 witnesses. 

In more than a thousand pages of new information in the case, some of those witnesses say the suspects were living Mary Ann's life, while her body was decomposing in the woods. For the family of Zarb, it's been an emotional and devastating ordeal from the moment Julie Temperly called 911 in April 2011, worried about her mom.

In a newly released transcript, the 911 operator asks if Mary Ann is known to go anywhere without telling her family. Julie replies, "No, never.  This would be her first time ever not talking to anybody...this is highly odd." 

Witness statements are among over a thousand new pages of information in the case. It depicts the suspected killers Shane Simpkins and Chris Neuberger living Mary Ann's life by using her car, credit cards and even taking the dog for walks. 

Tiffany Sipps was Shane's girlfriend at the time. She told investigators it's going around Suncoast that Shane and Chris did something wrong and it's fishy how they got the money.

Tiffany's mom was in the interrogation room with her daughter and said, "[Shane's] got all the money, he's got her credit cards. He's got all kinds of jewelry. He's got the dog. You think about it. He took that computer and sold it.  Why would you sell somebody's computer? If you know they're not coming back."

Simpkins and Neuberger are still awaiting trial.
