SEOUL \u2014 The death of North Korean leader Kim Jong Un\u2019s half brother remains a mystery, with Malaysian officials saying Tuesday that initial autopsy results show no evidence of a heart attack or puncture wounds.
In addition, no member of Kim Jong Nam\u2019s family has come forward to verify his identity through DNA or claim his body.
The developments add to the mystery surrounding the dramatic attack on Kim Jong Nam, who was ambushed at Kuala Lumpur airport last week as he went to check in for a flight and apparently had poison applied to his face, authorities said. Initial reports suggested that he had been injected with a poison needle.
Noor Hisham Abdullah, Malaysia\u2019s director general of health, said pathologists were still waiting for the results of lab tests to confirm the identity of the body and the cause of death.

\u201cWe have to confirm with the lab report before we can make any conclusive remark,\u201d he told reporters, declining to say when the lab results would be completed.
Noor Hisham also said that a second autopsy had not been conducted on Kim Jong Nam, contrary to widespread reports in the Malaysian media.
Authorities were also still waiting for a family member to come forward to provide DNA identification and claim the body. \u201cAt the moment, we do not have anyone claiming to be the next of kin; we are still waiting for them,\u201d Noor Hisham said.
Kim Han Sol, the 20-something son of Kim Jong Nam, was thought to have arrived in Kuala Lumpur on Monday night.
Local media reported that he was on a flight from Macau, where the family is based, to the Malaysian capital, and reporters staked out the airport for hours. But there was no sign of him. It is possible that he was whisked out via a private exit to avoid the media scrum.

North Korea and Malaysia have become embroiled in an increasingly acrimonious diplomatic row over the case.
Kang Chol, North Korea\u2019s ambassador to Kuala Lumpur, accused Malaysia on Monday of colluding with South Korea to try to make North Korea look bad and of committing \u201chuman rights abuses\u201d in the way the autopsy was conducted.
Malaysian Prime Minister Najib Razak responded that his government\u2019s probe would be \u201cobjective\u201d and that Malaysian police and doctors were \u201cvery professional.\u201d

North Korea strongly objected to Malaysia\u2019s decision to conduct a postmortem on Kim Jong Nam. It then accused Malaysian authorities of \u201cmangling\u201d the body.
North Korea has not confirmed the identity of the deceased as a member of the ruling family. The ambassador called him \u201cKim Chol,\u201d the name listed in one of the four passports that Kim Jong Nam was carrying when the attack occurred.
But Malaysian authorities have said that they are sure the victim is the North Korean leader\u2019s older half brother.
