Justice Ian Kirby found Moaro guilty of killing Lungile Ndlangamandla on the 27th February 2006 at her home in New Canada in Gaborone. The court found that Moaro was insane when he committed the offence. A psychiatrist who was called to testify, Dr NK Leech, who assessed Moaro on several occasions in 2007 and had interviewed some family members and friends, found that the accused was suffering from anti-social personality disorder (ASPD). The characteristics of the condition include inability to form loving relationships, criminal and anti-social behaviour, lack of remorse and sudden bouts of rage which lead to stress and speech impairment. She explained to the court that Moaro had been involved in minor criminal activities in the past and had shown no remorse for his actions. In one of the incidents, Moaro is said to have tried to strangle to death a dog that bit him on the ankle and had never shown remorse for such action. Dr Leech further told the court that though Moaro is ASPD patient, he was able to discern between right and wrong when he killed Ndlangamandla but it is possible that he did not realise what he was doing because of the rage that took him over. Justice Kirby and Moaro's mother also noticed that the accused had shown no emotion when he was testifying in court. "He told the court he regretted his actions, but his expression was flat," Kirby said in his ruling. He said that in response to the prosecutor's questions, the accused would only say that he had been confused, he did not know, or he thought it might be so but had admitted to all serious allegations of stabbing and stealing from his victim.According to evidence led in court, Moaro visited his aunt on the evening of 26th February 2005 to collect a debt for his mother. The aunt gave him some money to settle power and water bills for her. Moaro then agreed to come the following morning to bring receipts and return a computer accessory that he had borrowed from his cousin. Moaro, the only witness, confirmed that he visited her aunt's place at around 9am on February 27th and he found the deceased with whom he chatted about academic issues.
Both had failed, and an argument developed on who had failed worst and Moaro said in his confession statement that he lost his temper and slapped Ndlangamandla and she fell. "Her face turned bluish-purplish. I got scared. I don't know what happened with my head. I was confused thinking she was dead. I went to the kitchen and got a knife and put it in her neck. From there I ran to the bedroom and got a T-shirt. I wanted to commit suicide using the T-shirt but I found that the T-shirt was not suitable," Moaro said in his confession statement.
