Rukundo had met her husband 11 years earlier, right after she arrived in Australia from Burundi. He was a refugee from the Democratic Republic of Congo, and they had the same social worker at the resettlement agency that helped them get on their feet.
Since Kalala already knew English, their social worker often recruited him to translate for Rukundo, who spoke Swahili. They fell in love, moved in together in the Melbourne suburb of Kings Park, and had three children (Rukundo also had five kids from a previous relationship).
She had returned to Burundi, her birth country, from her home in Melbourne, Australia, to attend her stepmother's funeral. She lodged in a hotel. "I had lost the last person who I call 'mother. It was very painful. I was so stressed."she told BBC
By early evening, Noela had retreated to her hotel room. As she lay dozing in the stifling city heat of Bujumbura, her phone rang. It was a call from her husband in Australia
"He says he'd been trying to get me for the whole day," Noela says. "I said I was going to bed. He told me, 'To bed? Why are you sleeping so early? I say, 'I'm not feeling happy'. And he asks me, 'How's the weather? Is it very, very hot?' He told me to go outside for fresh air." Noela took his advice. "I didn't think anything. I just thought that he cared about me, that he was worried about me." But moments after stepping outside the hotel compound, Noela found herself in danger.
"I opened the gate and I saw a man coming towards me. Then he pointed the gun on me. He just told me, 'Don't scream. If you start screaming, I will shoot you. They're going to catch me, but you? You will already be dead. So, I did exactly what he told me."
The gunman motioned her towards a waiting car. "I was sitting between two men. One had a small gun, one had a long gun. And the men said to the driver, 'Pass us a scarf.' Then they cover my face. After that, I didn't say anything. They just said to the driver, Let's go. I was taken somewhere, 30 to 40 minutes, then I hear the car stop." Noela was pushed inside a building and tied to a chair.
"One of the kidnappers told his friend, 'Go call the boss.' I can hear doors open but I didn't know if their boss was in a room or if he came from outside. "They ask me, 'What did you do to this man? Why has this man asked us to kill you?' And then I told them, 'Which man? Because I don't have any problem with anybody.' They say, 'Your husband!' I say, 'My husband can't kill me, you are lying!' And then they slap me. "After that the boss says, 'You are very stupid, you are fool. Let me call who has paid us to kill you.'"
The gang's leader made the call. "We already have her," he triumphantly told his paymaster. The phone was put on loudspeaker for Noela to hear the reply. Her husband's voice said: "Kill her." Just hours earlier, the same voice had consoled her over the death of her stepmother and urged her to take fresh air outside the hotel. Now her husband Balenga Kalala had condemned her to death.
"I heard his voice. I heard him. I felt like my head was going to blow up. Then they described for him where they were going to chuck the body." At that, Noela says she passed out. As the gang's leader ended the call to Kalala, Noela was coming round. "I said to myself, I was already dead. Nothing I can do can save me. But he looks at me and then he says, 'We're not going to kill you. We don't kill women and children. He told me I'd been stupid because my husband paid them the deposit in November. And when I went to Africa it was January.
He asked me, 'How stupid can you be, from November, you can't see that something is wrong?'" He might have been a hit-man with principles, but the gang's leader still took the opportunity to extort more money from Kalala. He called him back and informed him that the fee for the murder had increased. He wanted a further 3,400 Australian dollars (£1,700) to finish the job.
Back at the hotel, Noela's brother was getting worried about her disappearance. He called Kalala in Australia to ask for $545 to pay the police to open an investigation. Kalala feigned concern and duly wired the money. After two days in captivity, Noela was freed. "'We give you 80 hours to leave this country. Your husband is serious. Maybe we can spare your life, but other people, they're not going to do the same thing. If God helps you, you'll get to Australia.'"they told her
Before leaving Noela by the side of a road, the gang handed her the evidence they hoped would incriminate Kalala - a memory card containing recorded phone conversations of him discussing the murder and receipts for the Western Union money transfers. "We just want you to go back, to tell other stupid women like you what happened," the gang told Noela as they parted.
"You must learn something: you people get a chance to go overseas for a better life. But the money you are earning, the money the government gives to you, you use it for killing each other!"
Noela immediately began planning her return to Australia. She called the pastor of her church in Melbourne, Dassano Harruno Nantogmah, and requested his help. "'It was in the middle of the night. I said 'It's me, I'm still alive, don't tell anybody.' He says, 'Noela, I don't believe it. Balenga can't kill someone!' And I said, 'Pastor, believe me!'" Three days later, on the evening of 22 February 2015, Noela was back in Melbourne.
By now, Kalala had informed the community that his wife had died in a tragic accident. It was the day he held a memorial service for her that she walked in on him "It was around 7.30pm," Noela says. "He was in front of the house. People had been inside mourning with him and he was escorting a group of them into a car." It was as they drove away that Noela sprang her surprise. "I stood just looking at him. He was scared, he didn't believe it.
Then he starts walking towards me, slowly, like he was walking on broken glass. "He kept talking to himself and when he reached me, he touched me on the shoulder. He jumped. "He did it again. He jumped. Then he said, 'Noela, is it you?'… Then he start screaming, 'I'm sorry for everything.'" Noela called the police who ordered Kalala off the premises and later obtained a court order against him.
Days later, the police instructed Noela to call Kalala. Kalala made a full confession to his wife, captured on tape, begging for her forgiveness and revealing why he had ordered the murder. "He say he wanted to kill me because he was jealous," says Noela. "He think that I wanted to leave him for another man." In a police interview, Kalala denied any involvement in the plot. "The pretence," wrote the judge at his trial in December, "lasted for hours." But when confronted with the recording of his telephone conversation with Noela and the evidence she brought back from Burundi he started to cry.
Kalala was still unable to offer any explanation for his actions, suggesting only that "sometimes [the] devil can come into someone to do something but after they do it, they start thinking, 'Why I did that thing?'"
On 11 December last year, in court in Melbourne, after pleading guilty to incitement to murder, Kalala was sentenced to nine years in prison. "His voice always comes in the night - 'Kill her, kill her,'" says Noela of the nightmares that now plague her. "Every night, I see what was happening in those two days with the kidnappers." Ostracised by many in Melbourne's African community, some of whom blame her for Kalala's conviction, Noela sees a difficult future for her and her eight children.
