Puf, es horrible todo, estuve buscando en wikipedia y leà unas cosas de las que no hablan en el documental que aclaran un poco ese punto:
"Vicki Hutcheson, a new resident of West Memphis, would play an important role in the investigation, though she would later recant her testimony, claiming her statements were fabricated due in part to coercion from police.[9][26]
On May 6, 1993 (before the victims were found later the same day), Hutcheson took a polygraph exam by Detective Don Bray at the Marion Police Department, to determine whether or not she had stolen money from her West Memphis employer. Hutcheson's young son, Aaron, was also present, and proved such a distraction that Bray was unable to administer the polygraph. Aaron, a playmate of the murdered boys', mentioned to Bray that the boys had been killed at "the playhouse." When the bodies proved to have been discovered near where Aaron indicated, Bray asked Aaron for further details, and Aaron claimed that he had witnessed the murders committed by Satanists who spoke Spanish. Aaron's further statements were wildly inconsistent, and he was unable to identify Baldwin, Echols, or Misskelley from photo line-ups, and there was no "playhouse" at the location Aaron indicated. A police officer leaked portions of Aaron's statements to the press contributing to the growing belief that the murders were part of a Satanic rite.[citation needed]
On or about June 1, 1993, Hutcheson agreed to police suggestions to place hidden microphones in her home during an encounter with Echols. Misskelley agreed to introduce Hutcheson to Echols. During their conversation, Hutcheson reported that Echols made no incriminating statements. Police said the recording was "inaudible", but Hutcheson claimed the recording was audible. On June 2, 1993, Hutcheson told police that about two weeks after the murders were committed, she, Echols, and Misskelley attended a Wiccan meeting in Turrell, Arkansas. Hutcheson claimed that, at the Wiccan meeting, a drunken Echols openly bragged about killing the three boys. Misskelley was first questioned on June 3, 1993, a day after Hutcheson's purported confession. Hutcheson was unable to recall the Wiccan meeting location and did not name any other participants in the purported meeting. Hutcheson was never charged with theft. She claimed she had implicated Echols and Misskelley to avoid facing criminal charges, and to obtain a reward for the discovery of the murderers.[3]"

Sobre Serial, que va, yo lo escuché a pelo con la transcripción al lado para mirar cuando no entendÃa algo bien, en general se entiende todo bastante bien, aunque algunas partes que son grabaciones tienen una calidad de sonido más cutrilla. Espero que en algún momento lo subtitulen porque merece mucho la pena.
