Ivy Radebe said her son, Bhekithemba Peterson Radebe, was killed in April 1991 at Nkanyezini, near Port Shepstone on the KwaZulu-Natal south coast.
He was allegedly killed on the orders of a local IFP leader, she said.
Her son had been chased and attacked by a group of men.
"He ran away and was chased until they caught up with him at the pemises of the Ngcobo family, who was my neighbour. He was stabbed and hacked to death with spears, bushknives and axes," she said.
She reported the murder to the police. "They just laughed at me, nonchalantly."
Radebe asked the commission to help find the killers and bring them to justice.
Earlier, Makhosezwe Elliot Mthethwa told the hearing he was shot and left for dead by three alleged IFP members when he was going to work on June 22, 1992.
Mthethwa, who lives near Port Shepstone, said three men he knew walked up to him and shot him.
"I was about 50 metres away from the bus stop when Majola, Mhlongo, and Nzama approached me from the opposite direction. I greeted them as per custom but they did not answer. They just opened fire," Mthethwa said.
He did not give their first names. He said he was shot in the left arm, right thigh and stomach.
"I knew the attackers very well, they were Inkatha members and neighbours.
"As I lay there, pretending to be dead, I heard them praising themselves for killing me because I had refused to go to these camps."
Asked what happened at the camps, Mthethwa said the men sat with traditional weapons, waiting for attacks from a rival political organisation which did not take place.
"I used to go often to these camps until I got tired and decided not to attend, and I was beaten up," Mthethwa said.
Another victim was ANC member Gcina Geoffrey Maphumulo, from the same area.
Maphumulo's son, Phila Aubrey Maphumulo, told the hearing his father was shot dead on July 2 1991.
He said his father was accosted by a group of men who told him to join them because they were going to a night camp.
"While he was getting ready to go the house lights were switched off and a torch was shone in his face. He was shot dead," he said.
He asked the commission to help find the killers.
