Paradise Lost - The Robin Hood Hills Murders

Echols is asking the Arkansas Supreme Court on Thursday to grant him a new trial. His lawyers want to present DNA evidence not available at the time of the trial, as well as testimony that supports arguments that Echols and the two others did not commit the crime.

Later this year, an Arkansas Supreme Court judge will determine if Echols and the rest of the West Memphis Three should have their convictions thrown out.

Prosecutors would then have the chance to retry them all and since they were sent to prison, the cases against them seem to have fallen apart.

Echols' attorneys plan to present DNA evidence not available at the time of the trial, as well as testimony that they say supports arguments that Echols and the two others are innocent.

(CNN) -- Three men convicted of killing three West Memphis, Arkansas boys in 1993 could be freed after a court hearing Friday, a person close to the case told CNN.

The men -- Damien Echols, Jessie Misskelley Jr. and Jason Baldwin are expected to attend the hearing in Jonesboro, Arkansas, on Friday.

A source close to the case said a deal is in the works where the men -- dubbed the "West Memphis Three" -- can be freed Friday and maintain their innocence.

The case has drawn national attention, with actor Johnny Depp and singer Eddie Vedder, among other celebrities, trying to rally support for the men's release.

The father of Steven Branch, one of the victims, blasted the apparent agreement.

"I don't know what kind of deal they worked up," Steve Branch told CNN affiliate WMC-TV. "Now you can get some movie stars and a little bit of money behind you and you can walk free for killing somebody."

But Misskelley's father said his son should never have been convicted.

"I'm just glad to get my son home, that's all I know," Jessie Misskelley Sr. told WMC.

The deal involves a legal maneuver in which the three men would have to acknowledge that the state has evidence it could use to try and convict them, the person close to the case said.

Echols was sentenced to death and Misskelley and Baldwin were given life sentences in the May 1993 slayings of Steven and fellow second-graders Michael Moore and Christopher Byers. The boys' bodies were mutilated and left in a ditch, hogtied with their own shoelaces.

Prosecutors argued that the men convicted, teenagers at the time, were driven by satanic ritual and that Echols had been the ringleader.

DNA later failed to link the men to the crime, and the state Supreme Court ruled in November that all three could present new evidence to the trial court in an effort to clear them.

The DNA tests were conducted between December 2005 and September 2007, according to the Arkansas Supreme Court.

The material included hair from a ligature used to bind Moore and a hair recovered from a tree stump near where the bodies were found, court documents said.

The hair found in the ligature was consistent with Branch's stepfather, Terry Hobbs, while the hair found on the tree stump was consistent with the DNA of a friend of Hobbs', according to the documents.

Police have never considered Hobbs a suspect, and he maintains that he had nothing to do with the murders.
