Pretoria – "For more than five years we’d planned our future together, but it’s clear God had a different plan for you. I will always be yours, even though you are not alive anymore.” With those words, a tearful Ronnel Mashinini said goodbye to the love of her life, Mbuso Nyambi, who was stabbed to death in his dorm room, Netwerk24 reported.Nyambi, a third-year electrical engineering student at the Tshwane University of Technology (TUT), would have turned 22 on December 13.A memorial service was held for Nyambi on the main TUT campus on Thursday afternoon.He was stabbed to death in the Lezard men's residence last Friday, apparently during an altercation with his roommate over a key. Hlulani Reuben Chuma, 23, was arrested and appeared in the Pretoria Magistrate’s Court on a charge of murder on Monday. He was released on R2 000 bail. Mashinini said she saw her boyfriend for the last time the day before his death."You didn’t say I’d never see you again. You didn’t say it was the last time. I still hope and pray that it is an awful nightmare from which I will wake. The grief is overwhelming."Samantha Zitha, a friend and classmate, described Nyambi as "loving and gentle". "He was like an older brother to all of us. He enjoyed life and brought much joy and love to others," she said. The acting director of extra-curricular development, Dr Edward Sedibe, said Nyambi’s death was unacceptable. "The university has buried three other students in the past six months. This is our fourth. It is unacceptable. We have to pray. The university needs God," he said. Genius Tshabangu, a member of the previous student council, said Nyambi had been forced to share a room because the varsity could not provide enough accommodation and security."Mbuso’s death was unnecessary," he said.Nkosinathi Maseko, president of the Pretoria campus, agreed."We blame the campus security services for his death. Where were they when a criminal attacked a good person?" Maseko asked. Nyambi would be buried on Saturday.
