Dennis Lynn Rader is an American serial killer and mass murderer who murdered ten people in Sedgwick County (in and around Wichita, Kansas), between 1974 and 1991.

He is known as the BTK killer "BTK" stands for "Bind, Torture, Kill", which was his infamous signature. He sent letters describing the details of the killings to police and to local news outlets during the period of time in which the murders took place. After a long hiatus in the 1990s through early 2000s, Rader resumed sending letters in 2004, leading to his 2005 arrest and subsequent conviction. He is serving 10 consecutive life sentences at El Dorado Correctional Facility, with an earliest possible release date of February 26, 2180.

One page (front and back) handwritten letter from Rader. Content of the letter is general conversation and is signed Dennis. Original matching handwritten manilla envelope which is sign in full  is included. The letter has been purposely blurred on the scan to protect the privacy of the recipient.

Rader items are very scarce on the true crime market making this piece highly collectible and great for display!
