Greg Biffle’s friends conspired to steal his wealth after he died, records allege
Friends of Greg Biffle conspired to steal his wealth after the Hall of Fame NASCAR driver, his wife, their two children and three others died in a Dec. 18 plane crash at Statesville Regional Airport, a sheriff’s search warrant alleges.
“It is the belief of this affiant that a plan has been in place by friends of Gregory Biffle and strategically executed after the death of the Biffle family,” an Iredell County sheriff’s detective wrote in a March 10 search warrant application filed in court.
Investigators found “multiple counts of fraud” on Biffle and his wife’s bank and other accounts, according to the warrant.
“This fraud appears to have been a strategic and coordinated strike against all accounts through multiple States which has resulted in hundreds of thousands of dollars being stolen.
“Evidence shows this would have to have multiple conspirators that had access to and intimate knowledge of” the Biffles’ accounts, “as well as their personal identifying information, ie social security numbers, birthdays, passwords, etc.”
Through multiple search warrants, investigators determined that people in the Biffles’ “inner circle may have been involved in the stealing of large sums of money from the Biffle’s accounts,” the officer wrote. “This leads the affiant to believe that a conspiracy has been in place for a long period of time to commit fraud against the Biffle family.”
Jan. 7 break-in at Biffles’ Lake Norman home
The officer said he believes that a Jan. 7 break-in at the Biffles’ home on Lake Norman in Mooresville “was a coverup to steal evidence of a more elaborate plan against the Biffle family and their wealth, not only of money but property as well,” according to the search warrant application.
The intruder spent “an extended amount of time inside the home” and stole $30,000 in cash, NASCAR memorabilia and two Glock handguns, sheriff’s officials said in a news release in January with photos of the intruder.
In the search warrant application, the officer also cited “the takeover of the financial accounts, email accounts, and the subsequent larceny of money owned by” Biffle and his wife, Cristina Grossu.
No one has been arrested in the case, which is under investigation.
Sheriff’s investigators matched the features of a person seen on surveillance video at the house break-in with those of a woman they saw at a Dec. 16 celebration of Greg Biffle’s life, according to the warrant. The woman was a friend of Grossu, a detective says in the warrant.
License plate readers showed the pickup truck of the woman’s husband near the Biffles’ home just before the break-in, according to the warrant.
Fraudulent activity on Venmo, S.C. bank accounts
“Suspicious activity” on an email and banking accounts owned by the Biffles started the day after the plane crash, the officer said in the warrant.
“Email addresses to accounts were changed, as well as phone numbers and passwords,” and “fraudulent activity” started on Cristina Grossu’s Venmo account, according to the warrant.
On Dec. 29, someone changed account information over the phone on Greg Biffle’s accounts at United Carolina Bank, the officer wrote. The next day, a fraudulent check was cashed at a UCB branch in Columbia, S.C., from a Greg Biffle account, the warrant states.
“Another three checks were attempted from the same account at different UCB branches in South Carolina,” according to the warrant, which doesn’t say if the attempts succeeded.
