It only took a few hours after he had buried his wife's body and dumped his daughters in oil tanks that the Chris Watts alibi began to fall apart.
This was largely due to the surveillance footage that his neighbor had of Watts on the morning of the murders, which showed him very clearly his truck back to his garage, loaded the vehicle and drove away.
Watts had told the police and his wife Shanann's friends and family that she and daughters Bella and Celeste had run away that day while he was at work, but footage proved that was not the case.
In fact, the footage did not capture anyone who left the house that day, but Watts.
In video obtained by DailyMail.com after filing a request under the Colorado Open Records Act, Watts is seen watching that video for the first time – and shoves his hands behind his head in disbelief when he realizes he's caught .

Hello, alibi: Chris Watts watched surveillance footage that allowed him to load bodies into his truck, a few hours after he had killed his family (above)
Not to go: the images showed that nobody left the house on 13 August, except for Watts, and when he realizes this he throws his hands behind his head in disbelief
Guilty: Watts starts to sweat and explains why he had to bring his truck to the garage that morning, which according to his neighbor was not normal
That video would later be used to draw Watts' confession before he was formally accused of murder.
After he had known, the process began with the retrieval of the bodies of his wife and two daughters, who were found despite his refusal to help in the search.
An illuminating report on hazardous substances submitted by the Colorado State Patrol provides details on the process of retrieving the bodies of Bella and Celeste Watts, 4 and 3, after being killed by their father and dumped in an oil tank.
The process of removing the bodies began at 5 in the morning of 16 August and would take almost 14 hours, with the report that at 6.45 pm the members of the Colorado State Patrol were on stage that evening.
At that time, the oil from the two 400-barrel tanks was hand-drained by workers, who carefully poured the liquid over metal screens to collect any evidence.
Once the tanks were emptied, men in independent breathing apparatus landed in the bodies of the girls, whose skin came off their bodies when they were taken out of the tanks.
Their mother and unborn baby brother Nico were found only 100 meters away in a shallow grave.
The report reveals that the diameter of the opening of the oil tank was only 8 inches, which means it was too small to fit into Shanann's body.
The troopers who came to the head of the collection process arrived around 9 o'clock in the morning of 16 August.
& # 39; While the first rough tank was being loaded, Trooper Bandy, Reeder and I have put rope handles on two containment pools & # 39 ;, Trooper Wilson wrote.
We thought that the bodies would be covered with crude oil and that they would use the pools to put each body in, once restored. & # 39;
After the tanks were emptied, the bolts on the tank doors at the foot of the barrel were removed by the team on site.
Sergeant Armstrong went to the top of the tank and looked into the thief, & # 39; reports the report.
Sergeant Armstrong told me he could see what looked like a body that was facing down on the south side of the tank. & # 39;
Photographs were taken and then the men started removing the body from the tank.
Because of the level of oil sludge and toxic fumes, the men could only stay in the tank for a few minutes, making the process much more complicated and difficult.
"Trooper Reeder first went in than I was right behind me. There was a body pointing down on the south side of the tank with its head facing west. It seemed to be a small female, & # 39 ;, according to the report.
Trooper Reeder grabbed the upper part of her right arm to turn her around. Trooper Reeder then lifted her up on both upper arms while I held her right leg. Trooper Reeder held her left arm and left leg as we led the body to the mangway. & # 39;
The victim was then removed from the tank, but during the process & # 39; outgrowth & # 39; she her skin.
That skin was outdated and given to a member of the police on the spot.

Unknown: the team could not identify the girls when they removed the two bodies, unable to tell the victims separately
Third body: the opening to the tanks had a diameter of only eight centimeters, which was too small to fit into Shanann's body, which Chris buried in a nearby shallow grave (Shanann's grave above)

The men then proceeded to remove the body of the second victim, which was found in the second oil tank.
I grabbed her right arm near the wrist area and moved her to the mangway. At this point, Trooper Reeder was able to secure her left arm and left leg. Trooper Reeder and I then passed the body through the manhole, & # 39; read the report.
& # 39; Trooper Bandy grabbed the left wrist and shoulder part, while Sergeant Armstrong did the same on the right side. When the victim was passed by the mangrove wing, Trooper Bandy and Sergeant continued to support her body when she was placed in a rescue basin. & # 39;

The report also notes: & # 39; During this extraction there was some slip on the skin where we had to touch the body of the victim. There was also some skin on the plywood where her back made contact. & # 39;
Some skin was also lost while the body was moved to the oil puddle.
& # 39; There was also a skin on the plywood where her back made contact & # 39 ;, says the report.
"Trooper Reeder and I then walked past the inside of that tank which also contained about 4 inches of raw sludge. We have not found any additional evidence in the tank. We left the tank and walked to the field south of the tanks. The body was transferred to the Weld County Coroner.
Sergeant Armstrong continued to follow the second victim, using a four gas monitor, when the Weld County coroner and pathologist tried to remove the crude oil using various oil-absorbing pads.
The second victim was then put in a body bag and taken to the vehicle of the Weld County Coroner. & # 39;
Bella was 4 and her sister Celeste had just turned 3 when they were murdered by their father.
Watts had told the authorities just a day earlier that it was his wife Shanann who murdered the girls and claimed that he had killed her in anger.
Two months later Watts changed his story and made a guilty plea in all three of the murders.
