The Heinz Park youngster, who was found guilty of five murders, all committed in the last three years, has psychopathic tendencies and has no place in society, a clinical psychologist told the Western Cape High Court on Tuesday.
Dr Hayden Knibbs says his report was based on his interaction with Wilson, and the aim of the report was to interpret and analyse the behaviour, evaluate the risk of re-offending and the most suitable sentence to be handed down by the court.
Wilson, 20, was convicted for the murders of Alfonso van Rooyen, Toyher Stober and Ernest “Ernie” Erasmus, all in 2014, as well as killing teenagers Stacey-Lee Mohale, 16, in 2015 and 18-year-old Lekita Moore last year.
Wilson, who was convicted of 13 of the 15 charges against him, grinned as Knibbs explained his “psychotic” behaviour to the court.
“The accused can be classified as a serial murderer. The classification of a serial murderer is: they cannot be rehabilitated, the accused is convicted of one murder whilst on bail and he willingly chose to conduct murders,” he testified.
“There is no chance of rehabilitation ever as young offenders are more likely to re-offend. I am of opinion that the accused currently poses a high risk to people and the most concerning risk factor is the psychotic behaviour displayed.”
Wilson was arrested in September in connection with the murder of 18-year-old Lekita in Valhalla Park while he was out on bail for the murder of Stacey-Lee in April 2015.
Knibbs explained that Wilson showed a lack of remorse for his crimes, instead shifting blame and responsibility, and his psychosis seems to be of a need for control and power.
“The crimes of which the accused has been convicted of were unprovoked, and he preyed on victims that had in no way harmed him,” said Knibbs.
Wilson blamed his friend Xavier Bester for Lekita’s murder, claiming it was he who raped and stabbed the girl 98 times. Bester was found murdered hours after Lekita’s body was found.
“The crimes seem to be about control over others, a sadistic desire to harm others and a possible need to impress; sometimes forcing others become reluctant participants for fear of their own safety.
“He appears to display a narcissistic sense of self-entitlement, that when bruised, causes him to act immediately in a murderous way,” Knibbs added.
Wilson was frowning as the word psychopath was bandied about.
The matter has been postponed to Monday to allow time for Wilson’s legal representative to prepare argument for mitigation of sentence.
