Coordinated Fraud and Burglary Scheme

Search warrants obtained by WBTV reveal that the January burglary of Greg Biffle's Mooresville home was likely coordinated with a broader bank fraud scheme targeting the deceased family's accounts. Detectives frame both crimes as potentially reliant on insider knowledge of the couple's accounts and daily routines. The investigation suggests the burglary and fraudulent banking activity were not isolated incidents but part of a larger coordinated scheme.

Extensive Financial Theft

While the January break-in involved theft of more than $30,000 in cash and two firearms, warrants allege that hundreds of thousands of dollars were stolen from Biffle family bank accounts following their death in the December plane crash. Fraudulent checks were cashed from accounts tied to Biffle's business interests, and suspicious activity occurred across multiple states and bank branches, suggesting organized criminal activity rather than opportunistic theft.

Evidence of Insider Knowledge

Search warrants indicate the suspect captured on security footage during the burglary demonstrated familiarity with the home's layout and the location of security cameras. This prior knowledge suggests the burglar had access to detailed information about the property, pointing toward someone within the Biffle family's inner circle. The warrants allege suspicious account activity began immediately following Greg Biffle and Cristina Grossu's deaths, including unauthorized changes to emails, phone numbers, and passwords.

Multiple Suspects Across State Lines

Iredell County detectives told WBTV that there are multiple suspects located across different states, though investigators cannot yet confirm whether they are connected. Several people in Greg Biffle and Cristina Grossu's broader inner circle are described in the warrant affidavits, though names have not been released pending arrests or charges. A person of interest has been identified, but no arrests had been made as of April 28.

Investigation Status and Evidence Gathering

Law enforcement executed search warrants on April 23 at a home in Lincoln County and a business in Mooresville. Electronic devices were seized from a residence in Denver, North Carolina, but no stolen items were recovered. Detectives have filed for search warrants related to email accounts, phone data, and property searches. Investigators continue analyzing evidence and awaiting results from seized electronics.
