The wife of the man who committed suicide after a court dismissed a case that followed the murder of their son made an emotional plea for help on Wednesday, as police said they were looking for flaws in the case.
"Thank you phu yai for your promise to look into the case. Please help us," Rewadee Thalahasuthon said in tears.
"I already lost my son. Now I've lost my husband," she said. "I have no more tears to cry."
The widow, her youngest son and relatives on Wednesday returned to the exact spot where Supachai, 52, died after plunging from the eighth floor of the Criminal Court building on Monday.
They performed a religious ceremony to guide his soul to Wat Kunnatee Ruttharam in Din Daeng district. The body was at the temple on Tuesday, after Ms Rewadee collected her husband's corpse from the Institute of Forensic Medicine at Police General Hospital.
Ms Rewadee is pinning her hopes on police to bring justice for her late husband and her son, Thanit.
The shock loss of her husband came after the court on Monday dismissed the case opened after the murder of the couple's son. Supachai, who was a co-plaintiff, committed suicide after the announcement of the ruling.
Thanit was stabbed to death on the night of April 15, 2016 in Din Daeng district. One suspect, Natthapong Nguenkhiri, was named in the case.
Supachai quit his engineering job to fight for justice for his late son, collecting footage from security cameras and other pieces of evidence. He was confident he had sufficient evidence to convict the suspect, and may have been bitterly disappointed after the case was dismissed, Thanaporn Sribanyen, a lawyer for Supachai, told Amarin TV.
The Office of the Attorney-General said prosecutors, who were a co-plaintiff along with Supachai, indicted the suspect based on the evidence and said the family still had a chance to pursue the case in the higher courts.
With Supachai's family yet to decide whether to appeal the ruling, the spotlight is now on the work of police after Metropolitan Police Bureau (MPB) Pol Lt Gen Chanthep Sesawet said investigators would review the case.
Deputy MPB chief Sompong Chingduang, who is in charge of the review, said the court's written ruling may be used to show flaws in the evidence presented to the court.
But Pol Maj Gen Sompong said it would be difficult to reopen the probe unless investigators discover new evidence.
Police from Din Daeng police station were ordered to the MPB on Wednesday, as the crime took place in its jurisdiction and the investigation began there.
Pol Maj Gen Sompong said he would be fair to both Din Daeng police and the family of the victims.
