Just weeks after Greg Biffle and six others were killed in a North Carolina plane crash, burglars reportedly stole $30,000 in cash from the former NASCAR driver's home, according to a police report obtained by WCNC Charlotte. The burglary was reported on Thursday, January 8, when the Iredell County Sheriff's Office responded to a call from Biffle's estate in Mooresville, North Carolina. The police report states that in addition to the stolen money, a backpack was also stolen. Sheriff Darren Campbell told the AP that guns and memorabilia were missing as well.
