Iowa Man Sentenced to 27 Years in Federal Prison

RAPID CITY - United States Attorney Alison J. Ramsdell announced today that Senior District Judge Karen E. Schreier has sentenced a Des Moines, Iowa, man convicted of Abusive Sexual Contact. The sentencing took place on May 16, 2024.

Douglas Hennigar, age 66, was sentenced to 27 years in federal prison, followed by 10 years of supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund.

Hennigar was indicted for Aggravated Sexual Abuse of a Minor and Abusive Sexual Contact by a federal grand jury in September of 2023. He pleaded guilty on March 15, 2024.

In 2010, Hennigar moved to the Pine Ridge Reservation after meeting the victims’ grandmother/mother through social media. The grandmother cared for multiple children, including her 10-year-old daughter at the time. Almost immediately after moving in with the grandmother, Hennigar sexually abused two female children, who were between the ages of 5-10. The abuse spanned multiple years and occurred on and off the Pine Ridge Reservation. At the time of the abuse, the youngest child was five years old, but did not disclose the abuse until she was 14 years of age.

This case was investigated by the FBI. U.S. Attorney Megan Poppen prosecuted the case.

Hennigar was immediately remanded to the custody of the U.S. Marshals Service.
