WICHITA, Kan. (AP) — A Kansas man has been ordered to spend nearly 49 years in prison in the fatal beating of his girlfriend’s toddler who died several months after state welfare officials received reports that he was being abused.

26-year-old Lucas Diel of Wichita was sentenced Tuesday for second-degree murder in the May 2018 death of 2-year-old Anthony Bunn. He died two days after he was found unresponsive in his Wichita home.

Anthony’s grandfather, Zak Woolheater, described Diel as a “monster” and recalled the horror of sitting next to the dying toddler’s hospital bed.

Woolheater’s attorney said in a court document filed last year that the state was aware of a previous abuse report involving Anthony and didn’t follow procedures.

The boy’s mother, Elizabeth Woolheater, also has been charged with murder.
