Euthanasia Attorney Sean Davison is expected to appear on the Cape Town Tribunal on Monday and face two foreseen murders.
Davison, the founder of DignitySA, was arrested in 2013 for the death of his friend, Friedrich Burger, who became a quadriplegic after a car accident.
News24 said that, according to a letter, the accuser "had fatally quadriplegic deaths" at or near the Radisson at Granger Bay on November 2, 2013.

Davison, who helped her mother quit New Zealand, revealed in News24 in 2014 that he had helped Burger do the same.
The second fee is related to Justin Varian's death in 2015. Varian suffered from motor neuron disease.
The state accuses Davison of "placing the bag over deceased heads and administering helium with the intention of helium deoxygenation and / or asphyxiation".

During his first trial appearance, despite an affidavit reading by his lawyer, Davison maintained that he was not guilty of any crime.
"It is, and I have always said, that I did not commit any crime, as stated in this case," read his lawyer Joshua Greeff.
Earlier this year, News24 said Davison was trying to raise around R2.8m to pay for its legal costs.
At the time of publication in February, a confidential account with his lawyers received around 4,000,000 gifts.
