april fools- i kidnapped bongo

so i work with this guy, edmond.

he and i both have stuffed animal friends (as do a number of people in the office, don't ask me why). my little duck is dexter, and his little 'monkey' is bongo.

for april fools day i kidnapped bongo, tied him up, took pics of him, and then hid him and sent this url demanding beer as ransom.

critical to my plan was the hope that there would be more than one suspect for the crime.

in fact there were three main suspects, including myself, as well as other theories:
1. bongo had turned into an alcoholic, run away from home, and was now demanding beer with which to quench his thirst.
2. edmond had hidden Bongo away himself in order to gain everyone's sympathy

at one point, some coworkers formed the bongo liberation front and sent nasty messages out to the kidnappers, which is why there is an extra message at the top of that webpage.

another co-worker of mine helped out, spoofed the email server, and sent an email from bongo to edmond asking him to please help.

in the end, edmond conceded and brought in beer for the captor. bongo was released without anyone knowing for sure who had kidnapped him and without any serious injury.

at this point, i am still a main suspect, and rightfully so. i'm trying to think of clever ways to reveal my identity without just admitting it openly. i'm trying to think of something that would be fun.

i thought about leaving the beer in the fridge and sending another anonymous email message to the team saying 'there's beer for everyone, from edmond'. my fear on this one is that no one will want to drink it for fear they will be implicated, or worse yet, sympathetic to the kidnappers.

so help me out- how do i let on that it was me, without just admitting it. any suggestions?
