TRIPOLI, Libya (From CNN) -- For more than three minutes, you see a mob of enraged men toss Moammar Gadhafi around like a broken mannequin. His body and face bloody, his black bushy hair a crazy mess, the 69-year-old is pummeled. His shirt is ripped open to reveal a pudgy belly.
The cell phone capturing the scene focuses on a gulf of red spreading across the Libyan dictator's backside as someone stabs him in the rear with a bayonet. It didn't take long before the video was uploaded to the Internet, and the world's news organizations were broadcasting it.
The end of the eight-month uprising in 2011, inspired by the toppling of regimes in Egypt and Tunisia, seemed to have come to a grotesque end on October 20th.
It's still not officially clear how Gadhafi died because there's never been a formal investigation, Human Rights Watch said Wednesday in a 50-page report that details his death and the events leading up to it.
The rights group has obtained witness accounts and examined amateur videos shot with cell phones. One of the famous images captured on the day the mob got Gadhafi shows a young man holding a golden pistol triumphantly in the air as he's cheered.
A storyline heavily repeated in the media is that the fallen dictator was shot in the head with his own gilded weapon.
The killing of Gadhafi and the fall of his Libya is a dramatic story, but it's missing one very important part.
The rights group says the militiamen who ravaged Gadhafi and captured, tortured and killed his loyalists are possibly responsible for war crimes because killing someone in detention is recognized as such under international law. HRW lambastes Libya's current transitional government, saying it has taken no serious steps in investigating or prosecuting anti-Gadhafi militias.
If Libya is going to truly rid itself of violence and extremists -- a timely demand considering last month's U.S. consulate attack -- justice, the group believes, must be meted out on all sides.
CNN reached out to Libyan authorities Wednesday for comment on the Human Rights Watch report, but none responded immediately.
In February 2011, protesters took to the streets in Libya. They demanded peacefully that Gadhafi step down. His 42 years of hardline rule had to end.
As rallies continued, Gadhafi responded by ordering his forces to fire into the crowds. The movement descended into a violent uprising that dragged on for months. By March, the opposition gained a foothold in the city of Benghazi. In response, Gadhafi's forces closed in on the city.
At the United Nations, the Security Council passed a resolution imposing a no-fly zone over Libya and authorized the use of "all necessary measures" -- except an occupation -- to protect civilians from the violence raging in their country.
In August, as Tripoli looked ever more fragile, Gadhafi, his crew and his sons jumped into cars and sped off in various directions. Khamis Gadhafi, active in his father's regime, was killed in a NATO airstrike as he tried to skip town.
Another son, Saif al-Islam, managed to make his way to the Misrata suburb of Bani Walid, surrounded by desert. Al-Islam later told Human Rights Watch that a NATO airstrike had left him mildly wounded. He was captured in November near Libya's border.
National security adviser Mutassim Gadhafi, another son, made it safely to Sirte, his father's hometown. That's where the dictator and his crew headed, also.
Senior security adviser Mansour Dhao was in tow, he told Human Rights Watch, as well as Gadhafi's personal guard, driver and a bunch of other bodyguards.
Libya's intelligence chief was there, but only briefly, because he was dispatched hundreds of miles to the south of Sirte. His job? He had to tell Khamis' mother that her son was dead. For some time, Gadhafi and his inner circle stayed in the middle of the city. But as the fighting intensified, they began moving from empty house to empty house, eating the food left in the cupboards, Dhao said.
The homes they sought shelter in had already been looted. As the weeks wore on, food was sparse. The medicine they had was running out. It was getting tougher to find water.
This group, who once dined in luxury, was subsisting on pasta and rice.
"Living (was) very hard... we didn't even have bread," Dhao recounted.
Gadhafi spent most of his time reading the Quran and praying.
"His communications with the world was cut off... no television, nothing," Dhao said. "No news. Maybe we could use the (satellite phone) and get some news from al-Rai, Russia Today, BBC or France 24. I mean, (we) could call people who watch those channels.
"We had no duties," he said. "We were just between sleeping and being awake."
The militias hunting Gadhafi were getting closer. And the dictator was getting moodier.
"(He was) becoming more and more angry," Dhao said. "Mostly he was angry about the lack of electricity, communications, and television, his inability to communicate with the outside world."
The men would sit with Gadhafi and try to calm him down.
"Why is there no electricity?" he screamed at them. "Why is there no water?"
By mid-October, Mutassim, one of the two surviving sons, decided enough was enough. He told the group in Sirte to meet at an ad-hoc clinic. They were going to try to escape. The plan was to break out around 3:30 or 4 a.m.
But it took until about 8 a.m. to load the supplies and the men who were wounded. By that time, anti-Gadhafi militia fighters had returned to their fighting positions.
Odds were stacked against the convoy, not least of all because it was unwieldy, including some 250 people.
