He's speaking out. It's been six years since the disappearance and death of 20-year-old nursing student Holly Bobo, and her brother Clint Bobo — who was the last person to see her alive — is opening up. In tonight's 20/20 episode, airing at 10 p.m on ABC, Clint recalls the moment he realized that he was considered a suspect in his sister's case.

Sitting down with anchor Elizabeth Vargas, Clint explained that local law enforcement almost immediately branded him as a suspect and he was searched the morning after she disappeared. “They did check me, I took my shirt off. [I] would’ve taken my pants off if they [had] asked me," the 31-year-old said in an excerpt from ABC News. "I was just shocked that they were looking at me, that they were asking me to do these things."

“At that time, I don’t think anybody even indicated that," he continued. "It was really just the first day, me being with law enforcement all night and just question after question after question and detail after detail — you know, just trying to pull any information out of me. Which I understand, it’s what they’re supposed to do."

His interview comes just days after Zachary Adams was convicted of the abduction, rape, and death of Holly, and sentenced to life without parole plus 50 years, according to USA Today. Jason Autry and John Adams were also arrested in connection with Holly's murder, and Jason even testified in the trial.

At the time of her death, Holly was a 20-year-old nursing student who lived with her family in Darden, TN. She was last seen on April 13, 2011, as she walked into the woods near her home with a man who was wearing camouflage. Clint had seen her interacted with the man, but at the time he thought it was her boyfriend, Drew.

During Zach's sentencing, Holly's mother Karen Bobo paid tribute to her daughter's memory. "She was the sweetest soul I have ever known in my life," Karen said. "A sweetness and kindness that many people can’t imagine."
