Jury selection is complete and witnesses are called to the stand in the trial of a man accused of killing his baby daughter.
32-year-old Matthew Blaz sat and often cried while listening to opening statements at his trial.
Blaz is charged with deliberate homicide, for allegedly killing his eight-week-old daughter, Mattisyn Blaz last August.
According to court documents, Blaz was at home with his two-month-old baby when the child suffered severe injuries, including a skull fracture.
Later in the day, while driving with his wife, the couple realized the baby had stopped breathing and she was transported to the hospital.
Soon after, she was pronounced dead.
Blaz told police a neighborhood boy had dropped the baby earlier in the day.
An autopsy showed Blaz's story was false and that the injuries to the baby were not accidental and instead a result of a homicide.
"Mattisyn Blaz died as a result of being shaken or impacted and shaken, and her brain, her skull cracked," said Samm Cox, the prosecuting attorney.
"He adamantly denies that he hurt his daughter,” said Deirdre Caughlan, the defense attorney. “And he denies that today ladies and gentlemen. At the conclusion, we are going to come and ask you to render a verdict of not guilty. Thank you."
After closing arguments, a recording of Blaz's 9-1-1 call was played for the jury.
The doctor who treated Mattisyn was also called to the stand.
The trial is expected to go throughout the week in Butte-Silver Bow County Court.
If convicted, Blaz can be sentenced to life in prison.
