Troopers are now questioning 60-year-old David Arnold. They want to know why he left California headed for Maryland and ended up here in North Texas. Several sources tell the I-Team this is a case of cargo theft. Produce is among many products typically targeted. Lumber, prescription drugs, electronics, and meat are others. “A lot of the products that are stolen are later sold on the black market,” explains Fred Lohman, the Director of Operations at the National Insurance of Crime Bureau in Irving.
