CORONA, Calif. -- Lori Bollong says she wants to warn other parents about the contents of emergency roadside kits after her son was suspended from school because of it.

Lori Bollong bought the kit for her 17-year-old son who drives 20 miles to an after-school job. But inside the new, unopened kit was a utility knife.

"According to them it's a weapon and there's no tolerance for weapons," said Lori Bollong.

Drug-sniffing dogs at Santiago High School detected Bollong's asthma inhalers inside his truck parked at school. That's when security opened a bag behind the passenger's seat and found the utility knife. Bollong says the principal warned him "not to bring weapons to school, that someone could get hurt."

"He said that I put it in there intentionally," said Robert Bollong, who was suspended.

But Bollong's family went right out and purchased emergency roadside kits from WalMart, Costco & Sam's Club and each carried utility knives just like the one that got Robert suspended.

"The intentions were never to get those kids in trouble, it was to keep them protected. As a parent, that's our responsibility," said Karen Johnson, Bollong's aunt.

Robert was suspended for five days, but because the matter has to be reviewed first, and the next school board meeting is not for six weeks, he's still missing school.

"This is a devastating thing. My son will not graduate from high school if he's out of school for a month and a half," said Lori Bollong.

Principals can decide whether suspended students will be allowed on campus in the interim.
