Police are preparing for hundreds, perhaps thousands of bikers expected to ride into Oak Hill Memorial Park in San Jose sometime next month to honor the memory of Jeff "Jethro" Pettigrew, the president of the city's Hells Angels chapter who was shot to death in a gun battle at a Sparks casino. There will be Henchmen, East Side Riders Car Club, Devil Dolls, Top Hatters and more. Alongside them, also paying their respects, will be members of the South Yard Heavy Equipment Crew. That is not a motorcycle club. It is the San Jose Department of Transportation's pavement repair team. They knew Pettigrew from his day job. To them, he was not the local president of a biker club that law enforcement sees as a violent criminal motorcycle gang. He was as a veteran backhoe operator who paved potholes. Hans Larsen, director of the city's Department of Transportation, said he was not even aware that Pettigrew was a Hells Angel. Nor did he care. "We have many employees who are motorcycle enthusiasts. What they do in their private lives doesn't concern us as long as it doesn't affect their work,'' Hansen said. "From what I am hearing he was a nice person with a good attitude, very professional in his work and he did it well.'' Funeral arrangements are still being made. And Pettigrew's shooting death Friday night at John Ascuaga's Nugget Casino, which has law enforcement on high alert for a brewing bloodshed between outlaw Advertisement motorcycle clubs, is still under investigation.
