RED BLUFF, Calif. -

The man charged with the death of a 7-month-old Red Bluff boy agreed to a plea deal Friday.  Brandon Branscombe had been charged with causing the death of Dylan Miller on Mother's Day 2013.  His trial was scheduled to start in September. 

In Tehama County Court, Branscombe agreed to a plea deal, and will face 30 years in state prison.

Branscombe was charged with causing the death of a child.  Investigators said Dylan died from multiple blunt force injuries to the head.

Outside the courtroom on Friday morning baby Dylan's grandmother said, "All we've been able to do for the last 15 months is take one step in front of the other and one breath after the next."

Friends and family members of Dylan's mother, Lacie Miller, wore t-shirts with Dylan's picture on it.

Miller said she is somewhat pleased with the 30-year deal and is glad the ordeal is over.

"It's acceptable at least he'll be close to 50 or something when he gets out and most of his life is going to be gone anyway," she said.

Miller also tearfully said she's thankful the case didn't make it to a trial.

"It's a good thing it didn't go to trial because it's been really hard for me to keep my composure. That's not something you get out of your head especially when it's someone you trust and loved and you thought you could build a life with," she explained.

Miller also thanked the community and the Tehama County District Attorney's Office for the help and support.
    
Branscombe was arrested in May 2013. Investigators said he beat Dylan several times with two different objects and left him unconscious in his crib, while his mother Lacie Miller was at work.  Miller returned home and discovered her son was not breathing.

Miller and Branscombe were dating at the time.
