Break in JonBenét case
Months before Karr's deportation, the Boulder District Attorney's office received copies of the suspect's emails from University of Colorado journalism professor Michael Tracey, who received the emails from a person with the email address "December251996 at yahoo.com". December 25, 1996, was the date of JonBenét's murder. At least one of the emails was signed with the signature "Daxis". The tracking of the author began sometime in June 2006.[41]
Armed with the email address and Internet provider, U.S. Immigration and Customs Enforcement (ICE) determined the general location of the suspect in Thung Maha Mek, a neighborhood in Bangkok, Thailand. At the time, the suspect's name was not known.[41]
The break in the case came when Karr sent an envelope to Tracey by regular mail with a return address bearing the name of a major throughfare in Bangkok, Thailand, but no number or cross street.[41] Tracey sent Karr another kind of mail – a photograph delivered to a Thai post office box. Agents arranged a controlled delivery and were ready to spot their suspect. The man who arrived to pick up the mail delivery was using a 21-speed bicycle, the purchase of which was mentioned in e-mails sent by the suspect. The agents followed Karr to his residence and learned his name.[42]
On August 11, 2006, they notified ICE officials, and from that point on, Karr was placed under surveillance by Thai immigration officials.[41] A sealed arrest warrant, signed by Boulder County District Judge Roxanne Bailin,[43] was sent by the Boulder District Attorney's office to officials in Thailand on August 15, 2006. The next day, upon receipt of the warrant, Thai immigration authorities revoked Karr's visa.[41]
