The son of Sen. James Inhofe (R-Okla.) has died in a plane crash, a person close to Inhofe and Defense Secretary Chuck Hagel's office confirmed Monday.

The plane crashed near Owasso, Okla., on Sunday afternoon, reportedly killing the pilot.

Reports on Monday traced the plane to a company that Dr. Perry Inhofe is associated with, but the victim has not officially been identified. KOCO-TV was the first to confirm that the younger Inhofe was indeed the victim.

"My thoughts and prayers are with Jim and Kay and their family as they mourn this terrible loss," Hagel said in a statement, according to multiple reports.

Perry Inhofe is an orthopedic surgeon who works in Tulsa.

The elder Inhofe, 78, recently underwent emergency heart surgery the kept him away from Washington during the government shutdown. He has said he will seek reelection in 2014.

Plane crashes have claimed the lives of two senators in recent decades -- Sen. Paul Wellstone (D-Minn.) in 2002 and former senator Ted Stevens (R-Alaska) in 2010. Missouri Gov. Mel Carnahan (D) was also killed in a plane crash during his 2000 Senate run.
