NEW: North Korea says it will reject autopsy results

Three arrests have been made after Kim's death but no autopsy results

CNN  — 

In the latest twist in the bizarre murder of Kim Jong Un’s half-brother, Malaysia says it won’t release the body to North Korea without DNA from the Kim family.

Selangor Police Chief Abdul Samah Mat said without DNA from a next of kin, they won’t hand over Kim Jong Nam’s body or release the autopsy report, which could reveal the cause of death.

But North Korea says it will “reject” the results of a “forced” autopsy which was not witnessed by its officials, according to a statement from the country’s ambassador to Malaysia, Kang Chol. The ambassador demanded the immediate release of the body.

Kim Jong Nam died after being attacked at Kuala Lumpur International Airport on Monday. South Korean officials claim he was poisoned.

Three people have been arrested so far in relation to Kim’s murder: an Indonesian woman, a Malaysian man and another woman carrying Vietnamese identification.

Four days after the killing, many questions remain unanswered. Here’s what we know so far.

What happened?

Kim was on his way to catch a flight Monday morning to see his family in Macau, where he’s lived since his departure from North Korea years ago.

The Chinese territory, a short ferry or helicopter ride from Hong Kong, is a popular gambling destination with mainland Chinese.

The exact details of Kim’s murder are sketchy but Selangor State Criminal Investigations Department Chief Fadzil Ahmat told Reuters Kim “felt like someone grabbed or held his face from behind.”

Kim felt dizzy and immediately went to an airport customer assistance counter, seeking medical help. They were concerned enough to take him to the on-premises clinic.

An ambulance was called to take Kim to the hospital, but he died on the way.

How was he killed?

No one is exactly sure how Kim died.

Initially, local media put forth reports of poison needles and deadly sprays, but it wasn’t even clear whether Kim was killed or had a heart attack.

Then on Wednesday, South Korea’s Lee Cheol Woo, the chairman of the country’s National Assembly Intelligence Committee, publicly declared Kim had been murdered.

The car of ambassador of North Korea to Malaysia leaves the forensic department at the hospital in Kuala Lumpur, Malaysia on Wednesday, Feb. 15.

Lee stated the former North Korean heir had been killed with poison by “two Asian women.” He didn’t reveal how South Korea had discovered this or what poison had been used in the killing.

The autopsy may have revealed more, but despite having been finished on Wednesday, no results have been released.

As of yet, Deputy Prime Minister Hamidi said no next of kin had come forward to claim the body.

Was North Korea involved?

No motive for the killing has been revealed, nor any explanation of how he was poisoned.

South Korea’s Lee told lawmakers on Wednesday that North Korea killed Kim but, again, he didn’t explain how he knew it.
