Mohlaki said he saw the weapon under the man's arm in the photograph he took, but when looking at the day photograph of the same body he said of the weapon: "It is not appearing, I don't see it."
Dali Mpofu, the attorney for the Lonmin miners, entered a video as evidence that showed miners that seemed to be handcuffed. When asked if he saw if any of the dead miners' hands had been bound, Mohlaki said he had not.
"If I am looking at the video there is a person, handcuffed possibly, but on the day I did not observe that," Mohlaki said.
The representative for the police, Ishmael Semenya, had suggested the week before that the integrity of the crime scene could have been compromised by the presence of paramedics, according to SAPA.
"We will hear evidence that paramedics asked that weapons be removed so they could do their work," said Semenya.
The inquiry began last month and is expected to continue for four months, investigating the roles played by police, miners, unions and Lonmin in the August deaths.
