Hans Nicholas Jong, Jakarta – Former National Police Traffic Corps (Korlantas) chief Insp. Gen. Djoko Susilo fumbled through explaining the origin of his immense wealth during a trial at the Jakarta Corruption Court in Kuningan, South Jakarta, on Tuesday.

In his defense against the money laundering charges leveled against him, Djoko provided a presentation detailing his assets, which were allegedly purchased using illicit money.

Hours into Djoko's presentation, presiding judge Suhartoyo questioned the legitimacy of the data, reasoning that when previous witnesses who knew about Djoko's assets testified, they could not provide evidence to back up their testimonies.

He asked Djoko: "What's the references of your data?" According to Suhartoyo, Djoko could have easily manipulated the data to match it with his indictment.

Responding to the panel of judges' doubts, Djoko insisted that the data regarding the cash flow of his businesses, which he claimed was the source of his wealth, was legitimate.

He, however, said he could not provide hard evidence regarding his cash flow as the transactions of his businesses were only based on trusts, and therefore were not documented.

"How could Rp 200 million become tens of billions of rupiah without any proper documentation?" asked judge Gusrizal Lubis, referring to the amount of money Djoko allegedly used as his starting capital.

Djoko is charged with graft and money laundering in his role in the vehicle simulator procurement graft case that caused Rp 144.9 billion (US$14 million) in state losses.

Last week, Djoko rejected prosecutors' demands to present all three of his wives in court and insisted that his marriages were his private business. He was afraid his wives would be put under too much psychological pressure if they were to testify in court, his lawyer, Teuku Nasrullah, said.

Djoko has three children with his first wife Suratmi, whom he married in 1985. He has another two children with his second wife, Mahdiana, whom he married in 2001. In 2008, Djoko, who was then 48, took teen pageant queen Dipta Anindita as his third wife, when she was only 19.

Djoko accumulated Rp 43 billion in assets between 2010 and 2012, using the names of his relatives, including his three wives and two children, Eva Susilo Handayani and Poppy Femialya.

During Tuesday's trial, Djoko tried to justify his decision to list his wealth under his relatives' names by saying that it was so that he could avoid paying progressive taxes.

Judge Pangeran Napitupulu then questioned why Djoko felt the need to avoid paying progressive taxes since 2007, when he started purchasing vehicles using his relatives' names, when in fact the tax policy started to be implemented in 2011.

Djoko explained it was a precautionary measure in case the tax policy was implemented early and added that some of his assets were purchased using Mahdiana's money.

When asked why he did not include Mahdiana in his wealth report submitted to the Corruption Eradication Commission (KPK), Djoko said he did not want to be accused of breaching the police's ethics code. "It is impossible for us as civil servants to expose our businesses, including reports on our wives," he said.

Djoko explained he did not use banking services in his businesses' transactions to avoid such a problem.

Hearing Djoko's reasoning, Gusrizal lambasted him for refusing to allow Mahdiana to testify before the court. "She used a lot of her money to buy the assets. But the data on her money management never appeared before the court," he said. "Then when we hoped she would appear in the court room [to explain the origin of Djoko's assets], you also refused."
