#CecilTheLion, hunted and killed by Walter Palmer, a Minneapolis dentist, is sitting atop the list of Twitter’s trending topics in the United States Tuesday night. A petition demanding justice for Cecil the lion in Zimbabwe currently stands at more than 143,000 signatures, while a “We the People” petition on the White House website calls for the arrest and extradition of Palmer to face prosecution for illegal poaching.

Palmer’s dental office was closed today, but protesters have tracked down his home address, with many posting it and his home phone number online.

These two “dentist hunters” tracked stuffed animals thrown onto Palmer’s lawn.

The story has been making the rounds of the world’s media, with international stations like Britain’s Sky News keeping an eye on Palmer’s home.
