Dennis Lynn Rader is an American serial killer who murdered ten people in Sedgwick County (in and around Wichita, Kansas), between 1974 and 1991. He is known as the BTK killer (or the BTK strangler). "BTK" stands for "Bind, Torture, Kill", which was his infamous signature. He sent letters describing the details of the killings to police and local news outlets during the interval 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 guilty plea. He is currently serving 10 consecutive life sentences at El Dorado Correctional Facility in Kansas.

Three photocopied poems on 4.5" X 5.5" sheets of paper. The front of the poems are photocopied but the backs are handwritten and NOT photocopied. Each poem is numbered, titled and initialed in Raders own hand. The envelope which contains the three poems is also handwritten and is signed Dennis.
