It was Joksimovic’s father who discovered his daughter had been murdered.
He became concerned after she didn’t pick her children up from school. He went to the house Joksimovic and Rieben shared and met the husband, a friend of the couple told the Daily Mail.
Rieben said he didn’t know where Joksimovic was. But Joksimovic’s father searched the laundry room and opened a bag, the source said.
“When [Joksimovic’s father] opened the black bin bag, he saw her cut off head with the hair still attached,” the source said.
Rieben arrived at court in a dark suit and white shirt, accompanied by his legal team.
His lawyer called him the “ideal husband”, while Rieben said he was “just trying to help and look after his wife”.

The father of two young children – aged 5 and 6 – faces life in prison if convicted.
At the opening of the trial, Rieben told the court he loved his wife – a former Miss Switzerland finalist – and her death was an accident.
“I have caused my family immeasurable suffering. Why? Why did I fail? Why couldn’t I prevent it? Why couldn’t I stop her from dying at my hands? I loved my wife with all my heart and believed in a future together,” he said, as reported by the Daily Mail.
“It haunts me day and night. What I did is absolutely unforgivable, and I take full responsibility. I deeply regret it, and I apologise.”

Professor Frank Urbaniok, a court-appointed expert, said in court that Rieben was diagnosed with narcissistic traits and obsessive-compulsive disorder, according to the Daily Mail.
He said Rieben had acted with “almost meticulous precision”, saying that after killing his wife, he had taken his two young children out for dinner and behaved as though nothing had happened.
“I have been working as an expert witness for 33 years and overseen 5000 cases,” Urbaniok said, the Daily Mail reported.
“I have seen many people who have committed homicides against intimate partners. But I have never seen anything like this before.”
The trial is expected to last five and a half days.
