A man who strangled his pregnant wife and suffocated their two young daughters wanted to escape his marriage and growing family, prosecutors said Monday as a judge imposed a sentence of life without parole as part of a plea deal that kept the killer from facing the death penalty.

Christopher Watts, who pleaded guilty two weeks ago, did not speak during the hearing. One of his attorneys said Watts was “sincerely sorry.”

As Watts listened with his head down, Shanann Watts’ parents detailed their ongoing struggle to understand how he could murder the three people who considered him a hero — Shanann, 34, Bella, 4, and Celeste, 3. Frank Rzucek said he was disgusted by the way his son-in-law took his wife and two daughters “out like the trash.”  “Prison is too good for you,” Rzucek said. “This is hard to say, but may God have mercy on your soul.”

Watts, 33, was formally sentenced to consecutive life sentences for the murders. He also received a 48-year sentence for unlawful termination of a pregnancy and 12 years each for tampering with a human body.  The girls’ bodies were found submerged in an oil tank on property owned by the company Watts worked for. His wife’s body was found in a shallow grave nearby.

As a prosecutor detailed the injuries found on the bodies, Rzucek leaned forward, gasping. Michael Rourke said Shanann Watts was strangled, but her lack of significant injuries suggested that her death came slowly.  The girls were smothered, and Rourke said there were signs Bella “fought for her life.” Celeste had no visible injuries, he said.

Christopher Watts’ parents, Cindy and Ronnie Watts, were permitted to speak as the girls’ grandparents. Each said they still loved their son and urged him to seek God’s forgiveness. “We love you,” Cindy Watts said into a microphone before turning to look directly at her son. “And we forgive you, son.”

Watts wiped away a tear with his shirt after his parents left the podium. He kept his head down for much of the hearing, speaking only once to confirm that he did not want to make a statement before Judge Marcelo Kopcow imposed his sentence.  Friends of Shanann Watts and neighbors in the subdivision where the family lived lined up inside the courthouse Monday morning. More people filed into an overflow room to watch a video stream.

Jell-O Play on Thursday introduced edible slime. The squishy and stretchy toy is a social media phenomenon, which spawned online recipes for edible versions.

Jell-O Play’s slime comes in strawberry-flavored Unicorn and lime-flavored Monster varieties. All customers have to do is add water and each canister makes two batches of slime. The company says it easily washes away with soap and warm water.

Jell-O says it launched Jell-O Play in the summer “to inspire families to engage in free play and fun.”

Edible slime will be available in select retailers in December or can be preordered online.
