HENDERSON COUNTY - Witnesses on behalf of the defense in the Randall Wayne Mays' Capital Murder trial took the stand.

And while more information unraveled in the courtroom, one of Mays' family members spoke to our crew outside.

She was Mays' first cousin Deborah Harris.

She waited outside with emotion.

Deborah Harris says, "I feel sorry for him and for the family's that were lost. I cried for weeks when it happened."

Defense Attorney Bobby Mims called Deputy Billy Jack Valentine back to the stand.

And again, more dash cam video.

This time-- revealing more details.

Let's go back to that day on May 17th, 2007-- the day of the deadly shootings on County Road 2529.

In the video, the defense singled in on Randall Wayne Mays saying this before shots were fired-- quote "You can kill me. Ya'll have killed all three of my brothers."

The defense attorney told the jury, Mays did have three brothers.

One was executed for capital murder.

The second was shot in a burglary.

And the third-- overdosed.

The defense argued Mays was affected by these past events in his life.

His cousin Deborah couldn't agree more.

Deborah says, "It's tore the family up, cause everyone of his brothers had been murdered. Every one of them."

Then there was this comment by Mays.

He said quote- "I'm really sick. I'm about to die anyway. I was poisoned."

Mays believes he was poisoned by the military.

The jury wasn't allowed to hear the next witness, Mays' psychiatrist.

She testified she took care of Mays when he was in the smith county jail, and says he is depressed, has borderline schizophrenia and paranoia.

Paranoia, which is a psychotic disorder, leads a person to believe in false beliefs.

For example, quote, "He may believe someone is poisoning his food, and that's not true. Or, that he may have a microchip under the skin."

She also says she's not sure how long Mays has been sick, but she says it is treatable.

Still, she admits, he hasn't been good about taking his medication.

Deborah says, "He needs them, he's a schizophrenic. He's a really good man, he's just had a hard life."

That's for the jury to decide.

Deborah says, "I think he should be locked up for the rest of his life, but I don't think he should be put to death, really he's already dead."

The Defense will pick back up Friday morning.
