A 45-year-old Olney man who robbed the same Lisbon bank - and same teller - twice during a three-week period last fall was sentenced yesterday to 20 years in prison.

Jeffrey Wayne Malcolm, who stole $9,150 from teller Deborah Nicholson's window at Westminster Union Bank, pleaded guilty to two counts of common law robbery in March.

"I know I did the wrong thing. I want to do the right thing," Malcolm told Howard Circuit Judge Diane O. Leasure in a halting voice just before she handed him a 30-year sentence, suspending all but 20 years, and five years' probation. "I'm sick and tired of this lifestyle, and I can't live it no more."

But Leasure, who noted Malcolm's long criminal record, called the robberies "reprehensible."

"It's hard for the court to imagine being robbed not only once, but twice by the same individual," she said.

In a statement read in court yesterday, Nicholson said that after the first robbery, which took place after she had been at Westminster Union Bank for three weeks, her family wanted her to quit banking.

A few weeks later, she gave her two-weeks' notice - but was robbed again before she could finish the notice period.

"Now I still don't sleep well and have very little ambition to go anywhere," she said.

Malcolm, who robbed the Old Frederick Road bank Sept. 20 and Oct. 11, was caught after a motorist saw him run from the bank during the second robbery.
