Father pleads guilty to murdering his pregnant wife and two daughters

(CNN) – A Colorado man, who killed his pregnant wife and two young daughters, pleaded guilty Tuesday as part of an agreement that would allow him to avoid the death penalty, said Weld County District Attorney Michael Rourke.

Chris Watts, 33, pleaded guilty to the nine charges he encountered, including murder and illegal termination of a pregnancy, for the murders of his wife, Shanann, in August, found in a shallow grave, and his two daughters, Bella ( 4 years old) and Celeste (3), whose remains were found in fuel tanks.

"I can only say that I hope there is a sense of closure [para los familiares de los fallecidos]"Rourke told reporters," I know this will never come true, because, of course, the tragedy that presents itself today is the loss of four wonderful lives, "he continued.

Watts is convicted on November 19 and lives in prison. Rourke said that the plea agreement asks the court to serve successive qualified moral sentences.

Rourke said that he had traveled to North Carolina a few weeks ago to discuss the possible agreement with Shannan Watts' relatives and that they had signed the abolition of the death penalty.

The mother, father and brother of Shanann Watts were in court, but chose not to talk to the media.

Chris Watts pleaded guilty to murdering his pregnant wife and two young daughters.

Rourke said he was unwilling to reject all accusations in exchange for the promise of guilty pleas.

"I was not willing to accept more concessions than the abolition of the death penalty," he said.

In his first interview with the police, months ago, Watts said that on the morning of August 13, he had told his wife that he wanted to seclude and then go to work.

In a second interview with the police, Watts said he looked at the baby's monitor and Shanann saw his daughter Celeste strangle and that she saw her eldest daughter, Bella, blue, & & # 39; lay & # 39; in her bed, according to the affidavit.

Watts told the police that he was furious and strangled his wife, according to the affidavit. He told them that he had taken the bodies and threw them in three places.

The researchers never believed his story, Rourke said.

The results of the autopsy have not been published.

Shanann, Bella and Celeste were missing on August 13 in Frederick, a city of about 8,600 people, 30 miles north of Denver.
