The 13 were part of an initial 32 who were charged with murder at the last sitting.
When the case was called on Thursday, the prosecution, led by Deputy Superintendent of Police (DSP) George Amegah prayed the court to discharge all accused persons, because further investigations have led them to charge 19 out of the 32.
He said some of them would be used by the prosecution as witnesses since they would be useful to the police and have been forth coming with information that has enhanced the investigations.
The rest of the 19 suspects which include one woman are now going to stand trial on charges of, conspiracy to commit crime to wit murder and murder.
The prosecution also told the court that 13 other suspects are currently at large.
The court then discharged the 13 based on the prosecution’s request.
Earlier, the prosecution informed the court that police investigations have revealed that, suspect Bernard Asamoah was not truthful to the court at the last sitting when he claimed to be 17 years.
DSP Amegah said the police went to the Circuit Education Office in Upper Denkyira, where his date of birth on his BECE certificate, indicated that he was born on April 1, 1995.
He said by that, the suspect is 22 years and not 17 as he told the court, adding that, his age was also confirmed by his father as 22.
The court adjourned the matter to July 19.
