The letter that was dropped in a UPS box at Second and Kansas Streets in October 2004 has been authenticated, according to Lt. Ken Landwehr, Commander of the BTK Task Force. "This communication contained information about BTK that was subsequently released to the public on November 30, 2004. The FBI can confirm that it is a BTK communication, but cannot confirm the accuracy of the information he wrote about himself in the letter," said Lt. Landwehr.

The other communication that the FBI has confirmed is from BTK is the package that was located in December by a Wichita resident in Murdock Park, said Lt. Landwehr. "This package contained the driver’s license belonging to Nancy Fox, which BTK took with him from the crime scene," Lt. Landwehr said.

Recent communications from BTK have included several items of jewelry. There was jewelry included in the Post Toasties box that was left on North Seneca Street, as well as in communication number seven, and in the package received yesterday by KSAS-Fox 24, according to Lt. Landwehr. The contents of yesterday’s KSAS-Fox 24 communication have been sent to the FBI.

"We are in the process of determining whether or not any of this jewelry belonged to our victims," said Lt. Landwehr.

During the first media briefing held last March after BTK resurfaced, Lt. Landwehr said that the BTK investigation is the most challenging case he has ever worked on, and that BTK would be very interesting to talk with.

"I still contend that this is our most challenging case, but I am very pleased with the ongoing dialogue through these letters," said Lt. Landwehr.

Since BTK resurfaced in Wichita last March, police have received more than 5,000 tips and leads from the public. Anyone with information on the case is asked to call 660-6440. Those calling from outside the local area may call 1-866-SOLVBTK (1-866-765-8285). Citizens can also e-mail information to mailto:coldcase@wichita.gov or they can mail information to Cold Case, P.O.
