Santos was reacting to recent reports that Zaldy has signified his interest to turn against his fellow accused in the Maguindao massacre case – father and clan patriarch Andal Ampatuan Sr. and brother Andal Ampatuan Jr.
According to the private prosecutor, their team already has enough strong witnesses to pin down members of the powerful clan and their militiamen who are all accused of killing 57 people and 32 journalists in Sitio Masalayat Barangay Salamn in Ampatuan town on Nov. 23, 2009.
In an interview with reporters, Santos cast doubt on the timing of Zaldy's supposed interest to turn into a prosecution witness.
"He should have done that earlier. In so far as we're concerned, we have enough witnesses to prove conspiracy so I think we don't need him," Santos said.
But the prosecutor admitted that it eventually would be a collective decision from all panel members whether or not to allow Zaldy to jump on board with other prosecution witnesses.
"Kelangan muna siya ma-arraign para malaman din namin kung ano ba talaga ang sasabihin niya," Santos said.
One and a half years after the gruesome killings, Zaldy is yet to be arraigned.
The Quezon City court could not yet read the charges filed against him because of a pending motion filed before the Court of Appeals seeking to remove Zaldy from the charge sheet.
The prosecution is now pushing for turning several of those accused into state’s witnesses, including Inspector Rex Alex Diongon and PO1 Rainer Ebus — both alleged to be present at the checkpoint where the Mangudadatu convoy was flagged down and the occupants were then killed.
