"The family will not discuss family issues or any matters relating to his passing with the media or in public," he said.
The details of Maila's alleged suicide were also confirmed by a staff member at the shooting range who was on duty on the day of the incident. The staff member, who asked not be named, said the incident has left them traumatised.
He said Maila was not under supervision as he presented the organisation with his firearm licence.
"He booked a week in advance. Upon arrival, he was calm although not very chatty. We showed him around, gave him a firearm and let him practice," said the employee.
"He shot himself in the mouth," he said.
An official of the health department, who also spoke to Sunday World on condition of anonymity, said Maila was going through a rough patch.
"He was living multiple lives and those lives were now colliding. Even the minister (Motsoaledi) knew about some of his problems. They tried to help him but he made them believe that he was coping," the official said.
Motsoaledi said he was not aware of the suicide allegations.
"I can't confirm or deny the information, because what we communicated as the department was what we were told by the police," said the minister.
He denied that he was privy to Maila's problems including that the deceased had approached him for advice.
