Authorities are investigating an alleged burglary at the home of NASCAR legend Greg Biffle, just three weeks after he and his family died in a plane crash in North Carolina.

Deputies responded to Biffle’s estate in Iredell County shortly after 6 p.m. last Thursday, the sheriff’s office said.

A backpack and $30,000 in cash were reported missing from the home, according to authorities. Firearms and memorabilia were also reported stolen during the burglary, sheriff’s spokesperson Dara St. John said.

No arrests have been made, and the case remains under investigation, the sheriff’s office said.

Biffle, his wife, Cristina, and their two children, along with three other people, died in a plane crash at Statesville Regional Airport in North Carolina on Dec. 18.

The plane crashed while it was trying to land on a runway at the airport just about 10 minutes after having taken off. The aircraft, a Cessna C550, was owned by GB Aviation Leasing, a company owned by Biffle, according to NBC affiliate WCNC of Charlotte.

The Federal Aviation Administration and the National Transportation Safety Board Safety Board are investigating the cause of the crash.

Biffle, a NASCAR Hall of Fame nominee who was named one of NASCAR’s 75 Greatest Drivers, won 19 NASCAR Cup Series races.

He was also a pilot, and he notably helped deliver supplies to victims in the aftermath of Hurricane Helene in North Carolina via private helicopter last year.
