The committee wants to hear testimony from Ravnsborg Chief of Staff Tim Bormann, who was with Ravnsborg the day after the crash when he discovered the body of the man he killed. Ravnsborg first reported the nighttime crash as a collision with an animal and insisted he did not realize he had killed Joseph Boever, 55, until he discovered her body when he returned to the scene the next day.

The House committee also subpoenaed David Natvig, who heads the Criminal Investigations Division under Ravnsborg, as well as the prosecutors who charged Ravnsborg with three misdemeanors, Assistant Hyde County Attorney Emily Sovell, and the Beadle County state attorney Michael Moore.

Ravnsborg in August did not contest two of the misdemeanors in exchange for prosecutors dropping the third charge.

Gosch said the committee would release unredacted portions of the accident investigation records before the committee releases its final report, but gave no timeframe for doing so.

Meanwhile, lawmakers also want to know who was behind a telemarketing campaign that last week tried to pressure them into impeachment, but they will leave that job to criminal investigators. They demanded that Ravnsborg recuse himself from the investigation and that it be handed over to a federally-run or another state law enforcement agency.

“There are serious implications,” Gosch said, saying the calls didn’t properly disclose who was funding them. “So state laws, federal laws that have been violated here. And if it’s criminal charges, that’s not really our jurisdiction.”

Lawmakers’ suspicions were piqued by a voicemail recording that Gosch said was left on a committee member’s phone and picked up audio from an Ohio call center supervisor.

Angel Kane, who owns and operates the call center called Grand Solutions, Inc., can be heard on the recording saying, “The Governor is actually involved in this, which is why it’s more accurate.”

A spokesperson for Kane, Jonathan Petrea, acknowledged that it was Kane’s voice on the recording, but said Governor Kristi Noem had not hired the call center, adding that “no politician, no political party, no campaign was part of the financing of the operation.”

He claimed Kane was using a motivational technique and pointed out that Kane did not use any pronouns to refer to the governor involved. But he declined to say who hired Kane’s firm, citing his client’s private life.

Both Noem and his campaign manager said they had no involvement in the telemarketing campaign.

Noem, a Republican, closely followed the committee’s work and harshly chastised lawmakers who looked into the work of law enforcement investigating the crash.

She said she was pushing for justice in the episode, which left criminal investigators doubting Ravnsborg’s account of the crash and Public Safety Secretary Noem publicly disapproved of prosecutors’ decision not to not press charges for manslaughter. However, if Ravnsborg leaves office, Noem will also be able to name his replacement.
