A man jailed for nearly two months in Grand Rapids was extradited Friday to California, where he faces charges of possessing pipe bombs, the Kent County Sheriff's Department said.

Scott Cristle, 34, is a suspect in 12 bombings over a 10-year period in Michigan and five other states, sheriff's Lt. Jack Christensen said. The U.S. Treasury Department's Bureau of Alcohol, Tobacco and Firearms is investigating the blasts, which killed one person and injured 21 others.Cristle, who was living in Salt Lake City before his arrest Aug. 20 in the Grand Rapids area, is suspected in a 1985 bombing that injured a University of Michigan worker.

The injured included a University of Michigan aide who opened a book-shaped package mailed to psychology Professor James McConnell in November 1985, authorities said.

Seven other professors, 12 passengers on an airline en route from Chicago to Washington, D.C., and a computer store operator also were injured in various explosions.

Many of the homemade devices were black powder pipe bombs placed in cigar or wooden boxes and triggered by a battery when opened, postal inspectors said.

Since May, Cristle has been in the Grand Rapids area, where he tried to find work as a computer operator before running out of money and moving into his car, Christensen said. Kent County sheriff's deputies arrested Cristle after a computer check on the car showed he was wanted.

Cristle has been held in the Kent County Jail on $100,000 bond.

Possession of an explosive device carries a maximum four-year prison term on conviction in California.
