A District of Columbia man who told Arlington police he had robbed nine banks in the area was convicted of one of those robberies yesterday by a Circuit Court jury that recommended he serve 60 years in prison.

The jury deliberated an hour before convicting Ricardo D. Jones, 26, of four counts of robbery, four of use of a firearm in commission of a robbery and one of entering a bank while armed with intent to commit larceny.

Four tellers of Continental Federal Savings and Loan, 4259 Wilson Blvd., testified that Jones entered the bank last Nov. 19 wielding a long-barrel revolver, threatened them and fled with $3,500.

Jones, of 1216 I St. SE, was arrested Nov. 28 and has since been held under $150,000 bond.

He is charged in three other Arlington bank robberies. A total of $28,000 was taken in the four Arlington holdups, according to Assistant Commonwealth's Attorney Liam O'Grady.

Defense attorneys Leon Demsky and Jeffrey Kleger argued that Jones, who told police he had used drugs regularly since the age of 13, was seized by an "irresistible impulse" to get drugs the day of the robbery and should be found not guilty by reason of insanity.

Frank Beckels, a psychiatrist at St. Elizabeths Hospital, testified that although Jones knew the difference between right and wrong on the day of the robbery and was aware of the consequences of his actions, "his will was completely obliterated by the dependency of chronic drug use."

Arthur Centor, a forensic clinical psychologist who interviewed Jones this week, testified for the state that Jones "was not suffering from a loss of volition . . . due to the effect of any drugs."

Judge Thomas R. Monroe set sentencing for Aug. 9. He can lower, but not raise, the jury sentence.
