Ricardo D. Jones, a Washington man convicted two weeks ago of robbing an Arlington bank, was convicted yesterday of robbing a second financial institution in the county. The jury recommended that he serve 112 years in prison.

The Circuit Court jury deliberated 2 1/2 hours before finding Jones, 26, guilty of four counts of robbery, three of use of a firearm in commission of a robbery and one of entering a bank while armed with intent to commit larceny.

Employes of the United Savings and Loan Association, 3709 Columbia Pike, testified that Jones entered the firm armed with a .22 caliber, long-barreled handgun Nov. 23, threatened a teller, the manager and three customers and fled with $1,400.

Jones, of 1216 I St. SE, Apt. 22, was arrested Nov. 28 and has since been held in Arlington County Jail.

He is also charged in the Oct. 22 robbery of Sovran Bank at 1425 S. Eads St. in Crystal City, in which nearly $20,000 was taken, and the Nov. 7 robbery of Sovran Bank at 3625 N. Fairfax Dr., in which $4,500 was taken.

Jones' court-appointed attorneys, Leon Demsky and Jeffrey Kleger, argued during the two-day trial that witnesses could not be certain whether the robber was Jones.

"The entire event did not last more than 10 minutes," said Kleger in opening arguments, questioning whether "somebody in an excited moment, with a gun in their face," could accurately identify a robber.

Assistant Commonwealth's Attorney Liam O'Grady argued that witnesses were able to identify the gun and briefcase Jones carried and were consistent in their descriptions of his size, clothing and build.

Judge Benjamin N.A. Kendrick, who may decrease but not increase the sentence recommended by the jury, set sentencing for Aug. 9.
