A couple's cross-country trip ended when they were murdered along a Texas beach. Their killers will now head to prison.

A New Hampshire couple was traveling cross-country but were murdered before they made it to their destination.

Now, their killers will head to prison.

Amanda Noverr and Adam Williams both pleaded guilty in connection to the killing of James and Michelle Butler. The killers pleaded guilty to murder and other charges are part of plea deals. Recently, a judge in Texas sentenced Noverr to 20 years in prison, according to the Caller Times.

Williams previously pleaded guilty and was sentenced to life in prison. His plea was to avoid the death penalty, according to KIIITV.

In October 2019, the Butlers were on a cross-country trip from New Hampshire when the suspects killed them in Padre Island, Texas, according to KIIITV. Padre Island is a popular tourist destination.

The Butler’s family reported them missing on Oct. 17 and the victims were found in a shallow grave days later.

Noverr and Williams was arrested after they were found driving a truck and trailer that belonged to the Butlers across the U.S.-Mexico border, the news station reported.

Prosecutors said the lighter sentence for Noverr was because she purchased the gun used in the killings, but did not pull the trigger, according to the Caller Times.

James Butler’s sister, Deborah Van Loon, previously stated the family’s lives were changed because of their relatives’ murders, according to the Caller Times.

"They have destroyed so much more than they will ever know," Van Loon wrote in a statement, according to the Caller Times.

Kleberg County District Attorney John Hubert released a statement to KIIITV after the sentencing.

"The family deserved closure and that Ms. Noverr answer for her part in the deaths of their loved ones. While she did not 'pull the trigger' she facilitated the crime, helped to cover up the crime and profited from it," Hubert said. "We also wanted to keep her influence away from her small child. In 15 years the child will be old enough to come to terms with the crimes of her parent on a better basis without having the corrosive influence of Ms. Noverr."
