The cases are being heard together.They face charges of murder, robbery with aggravating circumstances, unlawful possession of a firearm, unlawful possession of ammunition, and kidnapping.A fingerprint expert testified on Thursday that the prints he lifted from the hijacking crime scene in the Mahomed case and the ones he obtained from the investigating officer matched those of the accused.Ramohai was picking up her 12-year-old daughter from a Soweto school on Monday April 20, 2015. She had her seven-year-old son in the car with her when two armed men hijacked her in Bram Fischerville, Phase 4.They attacked her after her daughter got into the car.

Her children survived.The car was found abandoned in Dobsonville Extension 3 several hours later.“Each and every day that the matter goes on, it causes stress for the family,” Ramohai's husband, Tshepo, told News24 on Thursday.“It is better not to be here, but I need to be here to see what is going on. It's been a while since the incident happened and we are trying as a family. The children are now picking up the momentum when it comes to their studies,” he said.Mahomed was hijacked and killed 10 days after Ramohai.
