A toxicologist of the Ghana Standards Authority (GSA) has testified that the substance that was allegedly used to kill a former Upper East Regional Chairman of the New Patriotic Party (NPP), Alhaji Adams Mahama, was sulphuric acid with 93 per cent purity.
Mr Peter Quartey Papafio, who was testifying at the Accra High Court yesterday, said tests showed that sulphuric acid was the substance in a gallon presented to his outfit for testing by police investigators.
The witness said further tests conducted by him also revealed that a tracksuit trouser which was also given to him by the police for testing contained residues or traces of the sulphuric acid found in the gallon.
Prosecutors have made a case that the tracksuit was what Gregory Afoko, one of the accused persons, was wearing on May 20, 2015, when he and his supposed accomplice, Asabke Alangdi, allegedly attacked Adams Mahama with acid, leading to his death.
The said gallon is at the centre of the trial and one of the most important pieces of evidence being relied upon by the prosecution.
It is the case of the prosecution that the gallon said to contain the acid was allegedly abandoned at the crime scene by Afoko and Alangdi after the two committed the crime.
Alhaji Mahama suffered severe injuries after a substance was allegedly poured on him in front of his house in Bolgatanga around 11 p.m. on May 20, 2015.
He later died from the injuries.
