TheWrap‘s Hunter Walker has posted a grotesque story about Robert Sanchez, 36 year-old honcho of the recently defunct fanboy site IESB.net, having run for the hills over allegations of sexual misconduct with his step-daughter.

HE mentioned Sanchez twice in ’07 concerning (a) his being involved in a police-supervised sting that recovered Indy 4 photos that had been stolen from Steven Spielberg’s office, and (b) early-bird set photos of Robert Downey, Jr. in his Iron Man outfit that Sanchez posted but then took down due to legal warnings.

Sanchez “has gone missing for roughly three weeks after allegations of sexual misconduct with his underage stepdaughter,” Hunter’s story reports.

“Detectives were seeking Sanchez in connection with allegations of sexual abuse regarding ‘things to do with his stepdaughter and the internet,’ Tracy Dorsey, a spokeswoman for the Rancho Cucamonga police department, told TheWrap on Wednesday.

“Asked about rumors going around Hollywood’s digital movie media circles that the 36-year-old Sanchez had drugged and raped his stepdaughter and videotaped the act, Dorsey replied: ‘We’re looking into all of those allegations.’ She stressed that no charges have been filed, and there is currently no warrant for his arrest; nor has he been classified as a missing person.

Jamie Williams, one of Sanchez’ writers for IESB.com, resigned on Monday in a post on the site. Though the post is largely innocuous, he told TheWrap in an email Wednesday morning that he and the IESB staff were told a few weeks ago that there was a ‘family emergency/tragedy.’

“‘Then as of this past Friday evening, it was heavily implied that Robert had passed away,’ Williams wrote. ‘We agreed to stay on and help for the time being under these circumstances. It wasn’t until Monday evening we were aware of the details of Robert being on the run and his actions. And the icing on the cake was us being forwarded bills for IESB.’

“Sanchez’ whereabouts have been unknown for about three weeks, though he is not listed as a missing person.

“Sanchez lives in Alta Loma; his home phone had been disconnected. The IESB.net Twitter feed was taken down early this week.”

IESB is an acronym standing for “Inland Empire Strikes Back.”
