Shanann Watts, 34, and her two children Bella, 3, and Celeste, 4, have been missing since August 13, 2018, from Frederick, Colorado. In Aberdeen, he parents' next-door neighbor, Joe Beach, said he saw her recently.
The remains of all three victims were found at Anadarko Petroleum oil field, where Watts worked until his arrest, the Denver Post reported.
In an attachment to the motion, Merson included an e-mail in which Eikelenboom expressed his "expert opinion that DNA evidence would remain on the necks of the decedent children in spite of the fact that the remains were in oil for four days". A body believed to be Shanann Watts' was found first.
Watts was pregnant at the time, and Saturday was supposed to be "gender reveal" party for their third child.
Chris Watts initially pleaded for his wife and two daughters to return, claiming he didn't know what happened to them. They also asked the court to allow defense expert Richard Eikelenboom to take swabs from the bodies.
Watts was arrested Wednesday on suspicion of three counts of murder.
On Wednesday, police took him into custody.
Chris will be formally charged next week.
Police said they conducted a welfare check after Watts' friend called and requested one.
"When somebody kills their own family and then they go on TV to say 'But I didn't have anything to do with it, ' that ability to be so very sure of your own interpersonal skills that you can attempt to fool a national and worldwide audience is very unusual", said O'Toole.
Frederick police Sgt. Ian Albert said Shanann Watts and her daughters were reported missing at 1:40 p.m. on Monday by a friend who was concerned that she hadn't heard from the woman.
The two young girls Bella and Celeste and mother Shannan Watts were allegedly murdered by their father and husband on their Colorado property. Frederick police did not disclose the location of that well.
"Our hearts are broken for the loss of our dear friend Shanann Watts and her children".
"I don't want the horror to replace how handsome she was", Gentert said.
The mother, who was pregnant, and daughters vanished Monday from their suburban Denver home.
Watts was sacked on Wednesday, the same day he was arrested, an Anadarko Petroleu spokesperson said.
CNN affiliate KMGH aired video showing Chris Watts' pickup truck being towed from the family's home overnight, as well as investigators removing items from the house in garbage bags. I was hoping that I would just get ran over by the kids running in the door, just barrel-rushing me.
"If somebody has her and she's not safe I want them back now... if they're safe right now they're going to come back". "We were always impressed by his doting over them and how much he appeared to love them". "He is no longer an employee and given that the investigation is ongoing, please direct all questions to law enforcement".
