S4 E3: The Letters
Notas do episódio
October 1974: a phone call to the Wichita Eagle leads police to a letter hidden inside a library book — the letter in which a killer gave himself the name BTK. In this episode, Marcus follows the letters of 1974 to 1979: the library book, the 1978 KAKE television package, the poems, and the 1979 packages sent to Anna Williams, the woman who was not home — and why the letters stopped, and what they left behind. New episodes daily — one complete case every season. Music by SINIUS (Free Music Archive, CC-BY 4.0).
