A Tennessee Bureau of Investigation special agent testified that mistakes were made by the agency after the disappearance of Holly Bobo in April 2011.

Brent Booth, the agent assigned to the 24th Judicial District that includes Decatur County, said the agency had too much information coming in too fast and never checked the alibis of Zach Adams, Dylan Adams, Jason Autry or Shayne Austin in the days after the disappearance.

“It was a mistake not to check suspects’ alibis,” Booth testified. He said the agency was focused on Terry Britt.

TBI agents wiretapped Britt’s phone and homes, something that had never been done before in the state of Tennessee.

“We executed search warrants on his property, vehicles, out-buildings,” Booth said.

Booth said the TBI got a phone call in 2014 that changed the focus from Britt to the Adams brothers, Austin and Autry. It’s unclear who made that phone call.

“We went back to Day 1 and pulled out information that we had that we didn’t realize we had,” said Booth.

Booth said when investigators searched Zach Adams’ home in 2014 no trace of Bobo was found.

Booth returned to the stand in the afternoon after the lunch break.

For the first time in the case, the public also learned details about the alleged murder weapon.

Prosecutors only discovered the mysterious gun just a few months ago. It took investigators six years to find it.

Authorities found the gun with help from a man named Victor Dinsmore, who took the stand in the trial for Zach Adams on Friday morning. He said the weapon ended up in his hands just two days after Bobo vanished.

Dinsmore testified that he knew Zach Adams, Jason Autry and Shayne Austin back in 2011. He said he used to sell them morphine.

Two days after Bobo disappeared, Dinsmore said he gave Austin 12 morphine pills in exchange for a gun.

Dinsmore, who is not legally allowed to have a gun, testified that he gave his gun to his wife because he heard about what happened to Bobo.

He later called his wife and told her to get rid of it.

"Because I was worried it had a body on it, meaning I was worried it had been used to kill somebody," he said.

Dinsmore has a federal deal granting him immunity regarding any gun charges. He is a convicted rapist and a self-proclaimed former drug addict.

What remains unclear is why it took six years for investigators to find this gun.

Dinsmore told the jury he said to investigators that he knew the whereabouts of the gun used to kill Bobo long before her body had been found and before anyone knew she had been shot.

Only recently did the TBI fly Dinsmore back to Tennessee. They went to the location he described and eventually found the gun.

The defense questioned Dinsmore, trying to poke holes in his story.

Zach Adams' attorney has pointed out his past drug use and insinuated that the TBI coaxed Dinsmore into changing his story.

The defense also claims it was Dinsmore who got rid of the gun and not his wife.

During interviews with police, Dinsmore implicated another man for the disposal of Bobo's body.

Michael Alexander has an immunity deal as well and may be called to testify.

Testimony wrapped up around 3:30 p.m. on Friday. The trial will resume Saturday at 9 a.m.
