TRIPOLI, Libya - The body of former Libyan leader Muammar Qaddafi will be buried at a secret location in the Libyan desert on Tuesday, a National Transitional Council official told Reuters.
Qaddafi will be buried in a simple ceremony overseen by a Muslim cleric, Reuters reported. The news agency reported that negotiations failed over possibly returning Qaddafi's body to members of his tribe.
Qaddafi's son Mo'tassim was to be buried in the same ceremony.
The NTC official said that a decision had to be made quickly on what to do with the body, which was beginning to decompose.
Meanwhile, Qaddafi's remaining fugitive son, Saif al-Islam, is believed to be hiding near the borders of Algeria and Niger, trying to arrange an exit with a forged passport, NTC officials told Reuters. Neighboring intelligence sources claim Qaddafi aides are with him, trying to escape the country.
Earlier Monday, Libya's interim leader said he has ordered an investigation into Qaddafi's death in response to strong international pressure to determine how the ousted leader was killed by a bullet to the head shortly after he was captured alive.
Mustafa Abdul-Jalil told a news conference in the eastern city of Benghazi that the Transitional National Council has formed a committee to investigate Thursday's killing amid conflicting reports of how the dictator who ruled Libya for 42 years died. Government officials have said initial findings suggest Qaddafi was killed in the crossfire as his supporters clashed with revolutionary forces seizing control of his hometown of Sirte.
But Abdul-Jalil raised a new possibility on Monday, suggesting that Qaddafi could have been killed by his own supporters to prevent him from implicating them in past misdeeds under his regime.
"Let us question who has the interest in the fact that Qaddafi will not be tried. Libyans want to try him for what he did to them, with executions, imprisonment and corruption," he said. "Free Libyans wanted to keep Qaddafi in prison and humiliate him as long as possible. Those who wanted him killed were those who were loyal to him or had played a role under him, his death was in their benefit."

The body of the former leader was had been on display in an old meat locker in Misrata, with hundreds of Libyans lined up to take photographs, but was taken away Monday.
On Sunday, a local fighting unit held a press conference with Qaddafi's boots, golden gun, assault rifle and satellite phone as props, CBS News correspondent Elizabeth Palmer reports. They declared they'd done their best to keep him alive after his capture.
But new cell-phone video keeps appearing suggesting otherwise, Palmer reports. There's proof he was badly roughed up. In one video, a rebel, apparently on the scene, indicates to the camera, "Here's the man who killed Qaddafi." The autopsy only says that he died of a gunshot wound to the head.
has also analyzed a video taken shortly after Qaddafi's capture which appears to show a man sodomizing Qaddafi with a knife or similar sharp object.
Of course, there is the possibility that, if Qaddafi was executed and his killer were identified, that person would become a national hero and nearly impossible to prosecute, Palmer reports.
The U.S., Britain and international rights groups have called for an investigation into whether Libya's former rebels killed a wounded Qaddafi after pulling him out of a drainage pipe in his hometown of Sirte, the last city to fall to revolutionary forces after an 8-month civil war.
Critics also have said the gruesome spectacle of his blood-streaked body laid out as a trophy for a fourth day of public viewing in a commercial freezer raises questions about the new leadership's commitment to the rule of law.
Abdul-Jalil said the transitional government has established a committee to determine what ultimately to do with Qaddafi's body and the decisions will be governed by a fatwa, or religious edict, by the head of the Islamic Fatwa society.
Libya's revolt erupted in February as part of anti-government protests spreading across the Middle East. But Libya's struggle has been the bloodiest so far in the region. Mass protests turned into a civil war that killed thousands and paralyzed the country. Qaddafi loyalists held out for two more months after the fall of the capital of Tripoli in late August.
Abdul-Jalil declared the country liberated on Sunday, launching the oil-rich nation on what is meant to be a two-year transition to democracy. But he also laid out plans with an Islamist tone that could rattle their Western backers. He said Islamic Sharia law would be the "basic source" of legislation, and that existing laws that contradict the teachings of Islam would be nullified.
Using Sharia as the main source of legislation is stipulated in the constitution of neighboring Egypt. Still, Egyptian laws remain largely secular as Egypt's interpretation of Sharia does not cover all aspects of modern life, while Saudi Arabia and Iran apply much more strict interpretations.
Abdul-Jalil also outlined several changes to align with Islamic law such as banning banks from paying interest and lifting restrictions on the number of wives Libyan men can take. The Muslim holy book, the Quran, allows men up to four wives.
Mindful of the concern, Abdul-Jalil said Monday he was referring to a temporary constitution and said he wanted to "assure the international community that we as Libyans are moderate Muslims."
He also said there will be a referendum on a new constitution after it is drawn up.
