In the TBI press conference about Zach's arrest, law enforcement agents said they would not give details on what led to Zach's indictment.

This time, with the kidnapping and murder charges Zach faced, it looked like he might never be free again. Prosecutors were talking about pursuing the death penalty against him if he was found guilty. When his mom visited him in jail, she says Zach insisted he was innocent.
