A babysitter who injured a three-month-old girl and left her to die for 24 hours has been jailed.
Samantha Klein, 31, searched for symptoms of a seizure but failed to call for help after inflicting blunt force injuries to Alaya Foster.
The tot fell unconscious but despite having contact with the girl’s mother, Klein failed to seek medical help.
She finally called emergency services a day after the attack and Alaya was taken to hospital in Niagara Falls, New York, WIVB reports.
Alaya was diagnosed with a bleed on the brain, a fractured skull and spinal cord damage.
Despite best efforts from medics, she died from her injuries in hospital.
Neither the state’s prosecutor or Klein’s defence lawyer has given a motive for the attack, according to the Niagara Gazette.
Assistant District Attorney Holly Sloma said: “Everyone wants to know, why did she hurt her and why didn’t she seek help.
“She did this to a defenseless baby, and she did nothing — nothing — to seek help.”
The child’s heartbroken grandmother Crystal Dusen said Alaya never got to meet her father.
Ms Dusen said: “She’ll never get to smile or laugh, and her mother will never see her again.”
Klein initially denied any wrong doing before pleading guilty to first-degree manslaughter on October 15.
She was sentenced to 25 years in prison – the maximum jail term possible for the charge of first-degree manslaughter.
Klein was also jailed for seven years for a robbery charge and 30 months for a drug charge. The two additional sentences will run concurrently.
