Waukegan, IL-The child pornography charges against Larry Knapton are tied to the investigation into the murder of his estranged wife, Jone, but his attorney says the search warrant that found the alleged pornography is no good.

At a hearing Tuesday in Waukegan, Knapton's attorney argued that the search warrant used by Illinois State police was invalid. Attorney Jed Stone contends the 2003 search of Larry Knapton's Waukegan apartment and the seizure of several of his computers were beyond the scope of the search warrants signed by a Rock Island County Circuit Court judge.

Stone questioned Illinois State Police Investigator Chris Endress on the witness stand. ''You were looking for homicide evidence, you were not looking for child pornography,'' said Stone. ''We were looking for anything and everything that would relate to a homicide investigation,'' replied Endress.

Forty-one images of ''people who appeared to be under the age of 18,'' were found on Knapton's hard drive according to a state police analyst. ''There's no question that child pornography, if it's there, is a lucky find,'' said Stone after Tuesday's hearing.

Stone also is arguing that since the warrant had expired long before the computer hard drive was actually examined by a state police computer analyst, the warrant wasn't valid.

''If you're going to violate someone's right to be free from unreasonable search and seizures by having a search warrant, then you comply with the search warrant, our legislature says 96 hours, you do it in 96 hours,"said Stone.

Prosecutor Pat Fix said the computers were seized within 96 hours, but the analysis was not completed in that time frame, likening the situation to when DNA samples are taken, and then have to be sent to the lab and analyzed.

Jone Knapton disappeared from her house in East Moline over the Fourth of July weekend in 2003. Her torso was found floating in the Green River in Henry County on July 10th. Police don't have a crime scene, or know how Jone died because her head, hands, legs and feet, were missing.

Endress testified about some never before revealed details about the investigation. ''We have a receipt from Larry's work station that shows he purchased a reciprocating saw, sawblades, pen light and gloves in the Moline area at Menards.'' Endress didn't testify about the date on that receipt or if the saw had been recovered.

Larry Knapton declined to talk to NewsChannel 8 and ran from our camera. He has also declined to talk with police or Jone's family, which is his right. But Ashcraft says she won't stop until she has some answers.
