A Warsaw man who admitted beating his ex-girlfriend's 2-year-old daughter to death and burying her in a back yard could spend the rest of his life behind bars.
Kosciusko Circuit Court Judge Michael Reed sentenced Christopher Grimmett Thursday to 50 years in prison.
Grimmett, 30, had pleaded guilty but mentally ill to murder in the November death of Adalin P. Stamper.
The judge accepted a plea agreement signed by Grimmett, his attorney, Jay Rigdon, and Kosciusko County Prosecutor Dan Hamption. The deal called for Grimmett to receive a 50-year sentence.
A motion to seek an insanity defense was filed in February.
Kosciusko sheriff's deputies were called because of a custody complaint the evening of Nov. 10. Grimmett told police he had been baby-sitting his girlfriend's 2-year-old daughter, and that the child's maternal grandmother had picked her up.
Officers determined that wasn't the case and retraced Grimmett's steps to his brother's Sue Avenue home in Warsaw.
Police learned Grimmett was at his brother's home earlier in the afternoon with the girl.
Her shallow grave was discovered in the backyard after police obtained a search warrant from Grimmett's brother and sister-in-law.
Kosciusko County Coroner Tony Ciriello determined the cause of the girl's death was multiple blunt force traumatic injuries.
With credit for good behavior and time already served, Grimmett could be released in 2050.
