A D.C. Superior Court judge said yesterday that there was "overwhelming" evidence against a 26-year-old Washington man charged with the slaying of a bank teller and ordered the man held without bond pending action by a grand jury.

Judge Ricardo M. Urbina ordered William Oliver Hughes Jr., who is charged with murdering National Bank of Washington teller Sonya Grillo Durham, held after D.C. homicide Det. Michael Helwig testified that five witnesses to the Sept. 23 holdup had identified Hughes in a line-up and that Hughes' fingerprints were found in the bank.

Police and witnesses said Durham, a teller at the bank branch at 301 Seventh St. NW, was shot after she complied with a gunman's order to fill a bag with money. The gunman then collected money from several other tellers, thanked the bank employes, commandeered a taxi and escaped. According to an FBI official, about $20,000 was taken.

Police obtained a warrant for Hughes' arrest the next day after people telephoned to say they recognized the robber from photos taken by the bank surveillance cameras and reproduced in newspapers and on television.

Hughes surrendered to FBI agents in New Orleans two days after the holdup. Neither the money nor a gun were recovered. Helwig testified yesterday that Hughes had only $1 when he was turned over to D.C. police.
