A computer forensics investigator testified Thursday that he found child-porn images on the computer of former WNYW (NY) Fox 5 reporter Charles Leaf, shortly after Leaf’s arrest on charges that he molested a 4-year-old girl at his  home.

North Jersey.com writes that Yanal Bachok, a retired detective at the Bergen County Prosecutor’s Office, said in Superior Court in Hackensack that he conducted an investigation on a desktop and a laptop seized from Leaf’s home in 2010. He said he found that someone had performed a system restore on Leaf’s laptop to erase all the data on the hard disc. But a forensic investigation recovered thousands of photos, many of which were child-porn images, he said.

Leaf’s attorneys, meanwhile, have argued that there is no evidence that Leaf was the one who stored the child-porn images on the computer and no evidence that he was the one who performed a system restore to erase the data on the computer.

Leaf is on trial on charges that he touched a 4-year-old girl in a sexual manner in October 2010. Kenneth Ralph, an assistant Bergen County prosecutor, said earlier in the trial that the girl first informed her babysitter, who then contacted a family friend. The family friend called authorities, and Leaf was arrested after the girl told investigators during an interview that Leaf engaged her in sexual acts, Ralph said.

On the first day of Leaf’s trial two weeks ago, however, the girl — who is now 8 — took the witness stand and testified that Leaf never touched her in a sexual manner and that the babysitter had coached her into fabricating the allegations.

Leaf was charged with aggravated sexual assault, sexual assault and child endangerment. Prosecutors later added charges of possession of child pornography after finding images on his computer. He faces up to 20 years in prison if he is convicted of aggravated sexual assault, the most serious charge.

During cross-examination, defense attorney Emile Lisboa asked Bachok if he knew when those photos were viewed.

“No,” Bachok replied.

“Do you know who downloaded those images?” Lisboa asked.

“No,” Bachok replied
