Wearing a bulletproof vest and restrained by a police leash, Breivik returned to the Utøya island to recount his minute-by-minute actions that day. At times, he showed police how he had stalked his victims, even holding up his arms to demontrate how he took aim at those running away.

“We were able to animate his memory with regard to what happened out there,” said prosecutor Paal-Fredrik Hjort Kraby.

Although police said Breivik was “not unmoved” by being back on the island, “he did not show any remorse for his actions,” according to Kraby. Watch the video of the reenactment below:

New details about the massacre also emerged Sunday, including news that three Chechan youths tried to stop Breivik by throwing stones at him. One of the youths was shot dead, and the other two forced to flee.

Police also said they now think Breivik may have filmed the massacre, and they are now looking for his camera.

Breivik said he hoped TV newsrooms across Norway would screen parts of the footage, but some journalists had reason to believe TV stations wouldn’t show it:

Most Norwegian newspapers boycotted Breivik on their front pgs instead of cashing in on the tragedy #responsiblejournalism #RESPECTless than a minute ago via Twitter for Mac Favorite Retweet ReplyAysha Taryam
