Minburi Provincial Court on Thursday dismissed a case of alleged murder and making bombs without permission against a Chiang Mai teacher, 57-year-old Amporn Jaikorn.
Amporn is also a defendant in another bombing case at Samarnmetta Mansion in Nonthaburi in 2010 that is under appeal.
The dismissed case involves a March 2014 bomb blast in a Minburi playground that caused the death of two people and damaged a motorcycle.
During their investigation, police found that Kasi Ditthanarach, a defendant in the Samarnmetta Mansion case with whom Amporn had allegedly been in contact, had hired a room for the two killed in the 2014 bombing.
Amporn was then arrested in August last year at her house in Chiang Mai, and had been under detention ever since.
The investigators said the two cases were linked, but the court decided that neither the plaintiff nor investigators had witnesses who could confirm that Amporn had committed the crimes. Other witnesses could not pinpoint her as the woman who came to meet Kasi at the rented room.
The court thus concluded that testimony of the witnesses was not consistent.
Fingerprints found in the rented room were not Amporn’s. Citing weaknesses in the witness testimony and evidence provided by the plaintiff, the court found insufficient reason to convict Amporn and dismissed the case.
Amporn had previously been arrested in the Samarnmetta Mansion bomb blasting case and charged for possession of explosives, raw materials and firearms without permission. The case was dismissed but the prosecutor has appealed the case.
The blast at the mansion resulted in four dead, and 10 others injured.
Both cases had been linked by investigators to moves by “red shirts” in the street protests of 2010 and 2014.
