An East Texas man convicted of 34 counts of child sexual abuse was sentenced this week to life in prison — and then some.

Kevin Ray Morris Sr. will spend the rest of his life behind bars.

Jurors found Kevin Ray Morris Sr., 56, guilty of molesting, raping and threatening multiple children, ages 4 to 16, for more than 20 years, the Jacksonville Daily Progress reports.

The judge in the case ordered the 11 life sentences stacked, along with 450 additional years.

"You are a monster," Judge Chris Day told Morris. "If I could give you more time to serve, I would."

The Cherokee County district attorney's office credited Jacksonville police Lt. James Oden for helping put Morris away for good.

The detective discovered a trail of abuse that stretched into the early 1990s and refused to give up, even when Morris fled to Ohio. U.S. marshals ultimately arrested him there.

Many of Morris' victims testified against him at his trial, reopening old wounds to ensure that their tormentor would never walk free again.

"This case is a story about the bravery of children who were willing to stand up and fight," District Attorney Elmer C. Beckworth Jr. said, "and a detective who wouldn't give up."
