The clues we have: Radar Online and the National Enquirer say Corey's attacker is an A-list actor who is also the "kingpin" of a Hollywood child sex ring. Corey said he was abused when he was 14 when his attacker was 42.

Based on Corey's birthday, the attack was in 1986 (or Dec 85), which means the attacker was born around 1944. The Enquirer says the attacker hired (abuser) Brian Peck in the past.

D-nny D-Vito hired Peck for "Man on the Moon," and was born in 1944.

These two points alone are very significant.

Based on this some people thought it was Martin Sheen (although not as good on the age), but Kelly Oxford has specifically said it is not him, and that it is someone more "obvious. " D-Vito's humor is notoriously dirty, on "It's Always Sunny in Philadelphia" -- as in this skit about Not Diddling Little Children

By searching for his and Corey's name together, a superheroes forum came up where someone who may possibly be D-Vito posts prolifically -- 13,000 posts since 2011. Their name is subtitled "I am D-nny D-Vito" and their avatar image is the evil clown from IT.

There are many interesting screen shots -- here is one apparently discussing food that anyhow references "young cheese" He also has been commenting on the Weinstein case, and even the Haim case. He also mentions Bryan Singer and how no one cared. Screen caps below.

This person claims not to live in the US but also asserts and, indeed, demonstrates an insider's knowledge of Hollywood. He is a major D-Vito fan, and also claims to BE him in one example below.

I do not know if this is actually him or not, but it is of concern.

If this IS really him we should get as many screen caps as we can before this account is taken down. (Is there a way to bulk archive?)

(The site is kind of difficult to search at first -- you put in the username and search field, then complete the image puzzle, then scroll down and click "posts" and the button.)

It's not Martin Sheen, and it's someone more obvious: http://ohnotheydidnt.livejournal.com/103390908.html?page=4

D-nny D-Vito was definitely A-list actor in the 80s

According to this was 72 years old as of last Sept with 2 children, while this theory would say he was 71 then with 3 children: http://www.rigorousintuition.ca/board2/viewtopic.php?f=8&t=32827&start=75

Also note: Feldman said the event occurred on the set of "Lucas", but Haim always said he was 14 at the time, which makes it 1986 (or, a remote possibility, the last week of 85, though that wouldn't have been during filming). My thought is the attack may have occurred on the set of the Lost Boys, and Feldman is just doing a slight protective twist here. Haim always said he was 14.

So this is my theory. I do not claim that it is true, but that it merits further investigation. I think that is true, regardless of whether this online poster is in fact him, based on the good matches to the first clues above.
