Investigators said an anonymous poster on Internet forum Flashback claimed responsibility Thursday for the burning of the 42.6-foot-tall straw goat Wednesday night and a photo was posted on the site Saturday depicting four ankles bearing tattoos of a burning goat with the date and time of the arson, The Local.se reported Wednesday.
Police said the posts are their latest leads in the arson and vandalism investigation.
"This kind of tattoo isn't done by just anyone," police spokesman Mikael Hedstrom said. "But even if we find out who it is, it's no proof."
The goat, which was first erected in 1966, has been burned to the ground for most years of the tradition.
