COLLIER COUNTY, Fla. - The mother of a man accused of downloading hundreds of sexually explicit pictures and videos of children took the stand in her son's defense today. 

Daniel Guavara-Vilca's mother was living with him when he was busted in January 2010 for having child porn on three separate computers.

Before anyone could testify today, the jury had to finish viewing the child pornography evidence.

The Collier Sheriff's Office forensics investigator also got back on the stand.  John Kilpatrick told the jury more than one email profile was found on one of the computers, possibly indicating more than one user.

The defense continued to build it's argument that other people besides Guavara-Vilca used at least one of the computers inside his home.  Guavara-Vilca's mother lived with him at the time of his arrest, she testified in his defense, saying she always took a computer in the kitchen with her to work as a nursing assistant.

Carmen Guavara says the computer could be at a patient's home anywhere from a few hours to a week.  She also told the jury, members of her family would use any one of the three computers that were found with child porn.

When questioned about the file sharing network, Limewire, which detectives say was used to download the child porn, Guavara says she never used it before.

The jury was dismissed early.  Tomorrow they will hear closing arguments before deciding the fate of Guavara-Vilca.  If convicted on the the 464 charges he's facing, the 26-year-old could spend the rest of his life in jail.
