In October 1974 Lehnberg handed in her notice at the hospital and told van der Linde that she was going to leave Cape Town. On 24 October Lehnberg collected Choegoe from his home in
Retreat and drove him to Bellville in her car. He was armed with a hammer which was to be used to kill Susanna van der Linde. Lehnberg dropped him off in the vicinity of Boston and sped away. Shortly afterward Choegoe was spotted by Susanna van der Linde. She was alarmed because she had seen him in the area on more than one occasion. She telephoned the Bellville Police Station and Choegoe was picked up by the police about two blocks from her house. At the
police station he was beaten and warned not to return to the area. In the face of repeated failure Lehnberg decided to take matters into her own hands again. A few days after Choegoe's failed attempt, she approached Rob Newman, a 24-year old engineering student whom she knew, and asked to borrow his
Llama pistol. When he refused she asked if he would kill someone for her. Again he refused but on 28 October Newman's pistol was stolen from his room. He reported the theft to the police and suggested Lehnberg as a likely suspect. Around 8.30 a.m. on the morning of Monday 4 November 1974 Lehnberg arrived at Choegoe's home. She said that her car was packed and she was on her way to
Johannesburg, but before she left she needed Choegoe to come with her to van der Linde's house. He claimed in a statement that it wasn't until she handed him the Llama pistol on the way to Bellville that he realized that she wasn't just going to say goodbye. They arrived outside the house just after 9 a.m. Susanna van der Linde was alone inside. From this point on Choegoe's and Lehnberg's account of what followed differ.
Different accounts Lehnberg claimed that she got out of the car, rang the doorbell and returned to the car while Choegoe entered the house alone and committed the murder. Choegoe, however, maintained that they acted together throughout. Choegoe's account was supported by a neighbour of the van der Linde's, Mrs. Marais. On the morning in question, Marais had walked past Lehnberg's white
Ford Anglia twice in the space of ten or twelve minutes while it was parked opposite the van der Linde house and on both occasions the car was empty. Choegoe said that after Lehnberg rang the bell they went into the house together. When Susanna van der Linde saw them both she became frightened and threatened to phone the police. She attempted to get away, but was tripped by Lehnberg, fell and hit her head on the door. While Susanna van der Linde was on the floor Lehnberg struck her on the jaw with the butt of the pistol. On Lehnberg's instructions Choegoe began to throttle the semi-conscious Susanna van der Linde. Lehnberg then gave him a pair of scissors she had taken from the
sideboard. Choegoe said he remembered stabbing Susanna van der Linde three times but the
pathologist later noted seven stab wounds, six of which had penetrated the chest. After the murder Lehnberg squirted green dye over Choegoe using a gas pistol Susanna van der Linde had asked her husband to buy after she had seen Choegoe in the van der Linde's neighborhood. After warning Choegoe that she would deny any involvement in the murder if he went to the police, Lehnberg took him home. She set off for Johannesburg, collecting two speeding tickets at
Beaufort West on the journey. When the police brought van der Linde home to identify his wife he casually turned the body with his foot and said that it was his wife. This was reported at the time by the police officers present as appearing callous and almost as if he had been expecting it. It was suggested at the time that van der Linde had influenced Lehnberg in order to get her to murder his wife but this was not proven and he was never charged.
Arrest Choegoe kept both of the pistols that were used at the scene of the crime which were later seized by police. When he was asked why he hadn't discarded them he replied that it was dangerous to throw pistols away. Susanna van der Linde's body was discovered at about 1 p.m. by her daughter. van der Linde attempted to telephone his wife a number of times that morning and eventually became concerned when there was no reply. He spoke to his daughter Zelda, who worked at
Tygerberg Hospital, and asked her to go home during her lunch break to see if there was anything wrong. When she arrived home the house was locked up, but through a window she caught a glimpse of her mother lying on the floor in the living room. The police immediately began an intensive
murder investigation. Their chief suspect was "a crippled
coloured man" who had been seen in the area on at least two occasions prior to the murder. In fact, it was because of Choegoe that Susanna van der Linde insisted that her husband buy her a dye pistol. At first nobody considered that Lehnberg was involved or that she may have hired an
assassin. For the next week police efforts to establish Choegoe's identity and whereabouts proved fruitless. But at around 7.30 a.m. on 13 November a breakthrough occurred. Lieutenant Roland Fourie of the
Brixton Murder and Robbery Squad in Johannesburg went to see Lehnberg, who was staying at her uncle's house in
Bryanston and asked her to accompany him to
Brixton Police Station where he wished to ask her some questions. Lehnberg admitted on the way to the police station that van der Linde was her lover. She added that she had been expecting the police to contact her ever since she first heard about the murder of Susanna van der Linde from her mother. When asked if she had an association with "a
coloured man named Marthinus" she denied the allegation. Fourie also asked her if she had once requested a Robert Newman to give her his pistol so that she could get rid of Susanna van der Linde. Lehnberg admitted that she had, but that the request had been made in fun. Although Fourie had no specific evidence to tie Lehnberg to the murder it did strike him that she seemed unnaturally nervous at times during the interview. While Fourie was on the telephone to Cape Town another detective, Major van Aswegen, began asking Lehnberg questions. She suddenly blurted out that she took Choegoe to the van der Linde house, waited for him outside and took him home afterwards. Lehnberg was arrested and formally charged with the murder of Susanna van der Linde. Later that day she made a full statement in which she admitted that she had asked Choegoe, if he would
do away with Susanna van der Linde. In the statement she claimed that she had waited in the car while her accomplice had committed the crime. Choegoe was arrested the same day. The trial of Lehnberg and Choegoe began at the
Cape Town Supreme Court on 5 March 1975. The trial drew hundreds of spectators who fought for seats in the packed courtroom. After a hearing which lasted seven days, during which the State called more than 30 witnesses, the Judge, Justice Diemont and his two assessors, A.J. van Niekerk and F. van Zyl Smit QC, deliberated overnight and returned verdicts of guilty for both accused. The court found no
extenuating circumstances and Lehnberg and Choegoe were sentenced to death. == Appeal and imprisonment ==
