TrendPulse|FAA, NTSB investigating Utah plane crash that reportedly killed North Dakota senator

The TrendPulseFAA and NTSB are investigating a small plane crash that killed all four occupants – reportedly a North Dakota state senator and his family – on board in Moab, Utah, according to authorities and the Associated Press.

The single-engine Piper PA-23 crashed around 8:20 p.m. PT on Sunday shortly after taking off from Canyonlands Regional Airport, according to the FAA. The plane's registered owner was listed as Douglas Larsen of Mandan, North Dakota, according to the FAA aircraft registry.

Grand County Sheriff's deputies and Moab Fire Department personnel responded to the crash, according to a statement from the Grand County Sheriff's Office.

Just after midnight, the sheriff's office confirmed in a Facebook post that rescue efforts were completed and the four occupants on board did not survive the crash.

"Further information will be provided as soon as family members have been notified," the sheriff's office wrote.

Larsen, a North Dakota state senator, his wife and two children were the four people who were killed in the crash, the Associated Press reported, citing an email the outlet obtained.

"Senator Doug Larsen, his wife Amy, and their two young children died in a plane crash last evening in Utah," Republican Senate Majority Leader David Hogue wrote in the email to state senators, according to the AP. "They were visiting family in Scottsdale and returning home. They stopped to refuel in Utah."

ABC News has not confirmed the identifies of the four people who were killed.

Calls to Hogue and a Senate spokesperson were not immediately returned.
