GREENVILLE -- The prime suspect in the 2015 disappearance of a Wilson woman took the stand in his defense on Monday.      

20-year-old Isabel Palacios was last seen with Gregory Parks before she vanished and parks is now on trial for her murder.

When attorneys in a Pitt County courtroom asked Gregory Parks if he had anything to do with Isabel Palacios' disappearance, he didn't hesitate to answer.

Despite his denial, Parks remains on trial for what may have happened in Wilson in July 2015.

With a stack of evidence on full display the judge reminded the courtroom of the crime scene and 20-year-old's last known phone call.

Judge Wayland Sermons said, "He told me that he had received a phone call from his female friend screaming that there was blood on the windows. Then she hung up."

Eyewitnesses in 2015 said they last saw Palacios with Parks which led to this moment, where parks faces murder charges even though Palacios' body has not been found.         

Parks defiantly claimed his innocence, and said it would be obvious if he murdered Palacios.

“If I had done this, I would've robbed every bank from here to Miami, Florida and got away. But, I didn't do this. I didn't have to do that," he said.

Parks did admit in his testimony that he and Palacios had smoked crack cocaine in his bedroom before she disappeared...

He says anything Palacios did after had nothing to do with him.

There's no running from the courtroom either, and soon the jury will decide if they believe parks or not.
