Google tip-off, Facebookhunt

Cash was busted by police in Idaho after Google reportedan allegedly pornographic video involving children had been uploadedtohis Google Drive on five separate occasions in January and February 2016, the affidavit alleges.

"When Google finds sexually exploitive material, they report such contraband to [the National Center for Missing and Exploited Children or NCMEC], and capture the IPaddresses and account information," prosecutors wrote in the affidavit.

The roughly six-minute video shows a man rapinga pre-pubescent girl and another sexually assaulting a six- or seven-year-old, among other child sexual exploitation crimes, according to the affidavit.

Police tracked the IPaddress provided by Google to Cable One, an internet service provider in the U.S. The home registered to the account was unoccupied, but police located the account holder on Facebook.

It's unclear whether police are alleging this account belonged to Cash or an associate of his, as parts of the affidavit have been redacted.

Under the suspect's "friends" tab on Facebook, they found pictures of a man and woman with links to FetLife, a social networking site for people interested in BDSM, fetishism and kink.

Videos and cartoons

Investigators obtained warrants for two email accounts linked to the suspects, which yielded 28 gigabytes of information, but it wasn't clear from the redacted affidavit whether the accounts belonged to Cash.

Police allege they found a stash of illegal porn in the email accounts.

Peter would not tell us how long he has been downloading child pornography, but made it sound like it's been years.- Mike Nance, Office of the Idaho Attorney General

"I found 26 child pornography videos, with six of those videos having identified child victims through NCMEC," Officer Mike Nancewrotein the affidavit on behalf of the Idaho attorney general's office.

"I also found numerous cartoon-style drawings, with most of them showing young female children having sex with adult men or animals."

From the email accounts,police tracked down Cash's home address, using the latest IPaccount information registered with Cable One.

On May 18, police officers and Homeland Security agentsknocked on Cash's door and asked to interview him.

He co-operated, speaking to police for about two hours and 10 minutes in the back of their truck, and admitting to downloading child pornography, according to the affidavit.

"Peter would not tell us how long he has been downloading child pornography, but made it sound like it's been years," Nance alleged in the affidavit.

Nance allegedthat forensic detectives extracted 44 videos of child pornography from the computer in Cash's bedroom, and hundreds of photos from his phone during an initial search at the home.

A full investigation is now under way.

Cash arrested the day heplanned to leave for Canada

When Cash told police he was planning to leave for Canada that day or the next as soon as his passport arrived in the mail officers moved quickly to arrest him.

Idahopolice were able to identify a four-year-old boy in someemails of child pornography, and determined the child lived in the Red Deer areain central Alberta.

They contacted Canadian authorities, and on Wednesday, Red Deer RCMP arrested the child's 43-year-old mother, who worked at a licensed daycare in the city.

"This is a heinous crime that was committed on a young child by the one person they should be able to trust the most," said Insp. Dave Dubnyk, who oversees the internet child exploitation unit of the Alberta Law Enforcement Response Teams, on Thursday.

Dubnyksaid the Red Deer woman has been released from custody under "strict conditions to ensure she has no contact with her child," who isnow in the care of family members.
