Daniels, Lindon Wagner, Harvey Isha and Robin Harwood are on trial for murder and attempted murder, they have pleaded not guilty.
Theologo died in hospital a week after being doused with petrol and set alight in an alleged satanic ritual at a hill in Linmeyer, Johannesburg, in October 2011. Her friend survived the attack.
In their last court appearance on November 4, the court heard there was no scientific proof that brake fluid can cause disorientation if consumed.
Enrico Guarneri, for Daniels, told the court there had been no evidence to suggest that Theologo or her friend were ever given any medical treatment for consuming the fluid.
The court was told that Daniels was recruited to the soul-selling ritual just a few days before it was carried out.
Guarneri said his client had been consumed by curiosity, and did not think the other accused were serious about killing Theologo.
Earlier, Gail Sidwell, for Harwood, said in her closing arguments that he had been afraid to back out of the ritual as he had feared Wagner.
“He couldn’t just leave…. There was Lindon with a knife, and he had just seen him stone Kirsty,” she said.
