When Brandon Hyles arrived at Texas' Maypearl High School one day, a drug-sniffing dog targeted his truck, so a security guard searched it. He didn't find any drugs, but he did find an unloaded handgun under the seat. Hyles told the school officials he had no idea how it got there. And his father says he is telling the truth. Brian Hyles said he accidentally left the gun in his son's truck after borrowing it to go hunting. School officials said that makes no difference: Brandon violated their zero-tolerance policy on firearms on campus and is suspended indefinitely.
