A Casper man who broke the arm of a 20-month-old boy was sentenced to a three- to three-and-a-half year prison term during a hearing in Natrona County District Court on Wednesday.

Anthon Keevin Skansberg, 30, heard the sentence handed down by Judge Daniel Forgey.

Forgey accepted the terms of a plea agreement in October in which Skansberg pleaded guilty to a lesser charge instead of the original aggravated child abuse.

In exchange for the guilty plea, prosecutors also recommended the maximum three-and-a-half year prison sentence, and the dismissal of charges of child endangerment by methamphetamine and misdemeanor methamphetamine possession.

The case began in April when the victim with a broken arm was taken to the Wyoming Medical Center emergency room.

A doctor found that the child had three fractures, all in different stages of healing. The doctor took protective custody of the child and told police that "abuse was [a] very reasonable explanation for the injuries."

Skansberg told a detective that he did not cause the injuries.

In an affidavit of probable cause, the detective laid out a timeline of the child's alleged abuse, which spanned about four months.

On Jan. 19, 2018, the child was hospitalized for leg pain. The child also had a fresh black eye and skeletal scans did not show injury to the leg. At that time, Skansberg was dating the child's mother.

The child's babysitter told a Department of Family Services agent that the child had a black eye on Jan. 25.

In late March, the mother reportedly needed her three children picked up because there was no food in the home

A lump was found on the victim's right forearm, and was suspected to have been the result of a bite. Another bite, apparently from an adult, also was found on the child's stomach.

That same day, the victim's grandmother called DFS and said Skansberg was living with the victim's mother, but "he should not be around the children."
