SALT LAKE CITY -- Salt Lake County prosecutors have charged a babysitter with murder in the shaking-death of a four-month-old boy.
Thirty-five-year-old Jennifer Duran Martinez was charged Monday in Salt Lake City's 3rd District Court.
If convicted, she could spend the rest of her life in prison. An initial court appearance is set for Thursday.
Court papers say Martinez was babysitting Kaysen Calhoun on Sept. 22 when she became frustrated that he would not stop crying. She told investigators she picked the boy up and shook his head back and forth for an extended period of time. Martinez called 911 when the child stopped breathing.
He died Sept. 24 after being removed from life support
It was not immediately clear if Martinez had an attorney. She's held on $500,000 bail.
