Wichita A package purportedly tied to the BTK serial killings was found Tuesday after a local television news station received a postcard directing it to the scene, KAKE-TV reported.
The Wichita station broke into its afternoon programming to air footage of a cereal box leaning against a traffic sign along a Sedgwick County road but did not disclose its contents at the request of police.
Wichita police did not return calls to The Associated Press for comment. In the past, police have sent any reputed communications from the BTK killer to the FBI for authentication.
BTK -- which stands for "Bind, Torture, Kill" -- is linked to eight unsolved killings from 1974 through 1986. He resurfaced in March with letters to media and police.
The postcard mailed to KAKE had the name "S. Killett" and the address of BTK's first victims, the Otero family, written on the return address, KAKE reported. The sender called it communication No. 8, and asked whether the station had received the seventh communication.
In an open appeal to the BTK killer aired during its broadcast, the television station said it had not received the seventh message and urged the killer to contact the station.
