Long prison terms were handed out last week to two Washington men in connection with a type of crime that may become increasingly common in Washington and around the country — crimes with elderly victims.

One of the two men had been specifically convicted of armed robbery of a senior citizen, a category of offense that permits an added penalty under D.C. law. In the other case, one victim was 94 and the other 91.

In that case, Tony Ford, 48, also known as Anthony Ford, was sentenced Thursday to 231 / 2 years for posing as a maintenance man twice this year to get into apartments and take money, according to the U.S. attorney’s office for the District.

On June 19, a 91-year-old woman was punched in the mouth in her apartment in the 1400 block of Florida Avenue, prosecutors said. They said $23 was taken.

A week later, they said, a 94-year-old man was slammed onto his bed in an apartment in the 1200 block of G Street. About $133 was taken, the prosecutors said.

They said Ford had pleaded guilty in August in Superior Court to two counts of first-degree burglary and a firearms charge.

In the other case, the prosecutor’s office said, James Forte, 59, was sentenced Friday to 23 years after his July conviction in a knife-point robbery of a man walking a dog in the 1600 block of 21st Street NW in April.

The victim was described as a senior citizen, but no age was given.

Prosecutors said the sentence reflected not only the April robbery but other offenses, including an earlier robbery of a senior citizen.

In cases in which a victim is 60 or older, D.C. law permits a sentence of 50 percent more than otherwise authorized for the underlying offense.
