One year ago, a newborn baby was brutally beaten to death, killed at the hands of his own father. Thursday morning, he was sentenced to fifteen years to life in prison for what he admits he did.

Dylan Meng said a few months ago when he pleaded guilty to murder in the first degree that he came home from work feeling frustrated and he took it out on his baby.

Dylan Meng didn't go to trial for the murder. He took full responsibility all along, and at his sentencing hearing, he was ready to accept the sentence the judge was going to hand down. The 15 to life was the agreement made in a plea deal between his public defender and the prosecutor.

On July 10th 2008, Dylan was watching his two month old son Alex at their home in Ucon while his wife went shopping. Meng says the baby was crying, and he grabbed the child by the neck and shook him, abused his private area, and broke his femur. He also dropped the baby on the floor and strangled him.

Bonneville County Prosecutor Dane Watkins Junior said there is no greater crime than taking a life and that the baby suffered a violent death.

Dylan's mother Raylene told Judge Jon Shindurling that her son has struggled with mental issues since the age of 19. The problems began while he was on his mission for the LDS Church.

Raylene Meng: "The events that took place on July 10th of last year were real tragic for our family. Not only did we lose our grandchild but in essence, we lost our son as well."

She asked the judge to consider his mental problems in the sentence.

Meng was asked if he had anything more to say, and he declined to comment.

Judge Shindurling says this was an all around tragedy in every way and was bothered as he read the reports of how the infant was beaten from head to toe. The judge said the mental illness does not outweigh the fact that a life was taken.

With the minimum sentence of 15 years, Meng will not be eligible for parole until he's 52 years old.

In the courtroom were not only some family and friends for Dylan, but also a handful of members of law enforcement with the Bonneville County Sheriff's Office who worked this difficult case. They were interested in watching this killer learn his fate and see justice served.
