Mechanic killed repairing bus on freeway

A 32-year-old mechanic from Ramona was killed when a car plowed into the broken-down school bus he was fixing alongside a rain-drenched freeway Thursday. A 2005 Nissan Altima veered off the Interstate 805 in North Park and struck the San Diego Unified School District bus from behind shortly before 7 a.m., according to the California Highway Patrol. The mechanic was trapped under the hood for half an hour until firefighters pried it open. The crash left the motorist, a 41-year-old woman, seriously hurt and the repairman gravely injured and wedged in the engine compartment of the bus, CHP public-affairs Officer Art Athans said.
