The two men accused of kidnaping a Carroll County pharmacy clerk and holding her for eight days were returned to Maryland to face charges yesterday after surrendering to Pennsylvania state police Thursday.

Jimmy Edward Simpson, 39, and Olon Hill Jr., 36, waived extradition at a hearing yesterday morning in U.S. District Court in Harrisburg and were driven back to Maryland by FBI agents. They were interviewed at the state police barracks in Westminister, and later appeared before Carroll County district court commissioner Norma Doxzen.

Hill was charged with kidnaping, robbery, a weapons offense, theft and conspiracy and jailed in the county detention center in lieu of $750,000 bond. He said he had been unemployed for the past 14 months and asked to be represented by a public defender.

At a later hearing, Simpson was charged with the same offenses and also jailed in lieu of $750,000 bond. A bail reduction hearing before a General District Court judge has been set for 9 a.m. Monday

The two turned themselves in outside a rural store near Orrtanna, Pa., where Hill lives. Their arrests capped a nine-day nationwide manhunt, and came 36 hours after Patricia A. Hively was released in nearby Gettysburg.

Hively, a 41-year-old grandmother, was abducted May 10 during a robbery at the Taneytown Pharmacy, near the Maryland-Pennsylvania line, where she works as a clerk. Investigators believe she may have been taken as far as Tennessee, where, according to authorities, a store was held up in Rutherford County. Hively spent much of her ordeal blindfolded.

Police said Simpson and Hill apparently surrendered because they feared they would be shot when a contingent of heavily armed state police arrived to search a house they had been occupying near Orrtanna.
