BATON ROUGE, LA (WAFB) - Michael Louding, also known as "Marlo Mike," was scheduled to be in court Monday morning for the first of five status hearings, but the proceeding was delayed.
His next hearing is scheduled for the end of the month.
Louding, 19, is connected to six murders between February 2009 and April 2010.
Investigators said the then 17-year-old confessed to six murders back in May 2010.
The district attorney's office promised him less than life in prison if he gave truthful testimonies against other people connected with some of those murders.
"We had anticipated that he was going to continue to cooperate and provide testimony, not only to previous cases, but cases that are to come," said District Attorney Hillar Moore. "And apparently, that is not going to be the case."
The last time Louding was in court, he was the prosecution's star witness in the first-degree murder trial of Baton Rouge rapper Lil Boosie, whose real name is Torence Hatch.
According to Moore, Louding's deal is now off the table after lying on the stand during that trial.
"So, we are prepared to go forward and I'm assuming that we will have a trial date set fairly soon," Moore added.
Louding faces six life sentences if convicted.
