Speaking to the Sunday Independent, Crouch said a cold case arises when an investigation yields no results because of a lack of sufficient evidence.
“Police have got nothing in their investigation,” said Crouch, a certified criminal investigator and a certified computer forensic examiner.
“With murder cases you generally have a 48-hour window to develop your leads. After the first 48 hours every hour that goes by without leads generated or a suspect in custody makes it less likely that the case will be solved.”
Meyiwa was shot dead during an alleged armed robbery at his girlfriend Kelly Khumalo’s home in Vosloorus in October 2014.
After almost three years, no suspect has been arrested in connection with his murder.
New Police Minister, Fikile Mbalula, however, has promised that the police will soon crack the Meyiwa case.
“It is one of my priorities to crack this case with the team. I’m very positive we’ll make arrests, but I don’t want to tip them [the killers] off by divulging the plans we are going to use,” Mbalula was quoted as saying by IOL.
