The jury of nine women and three men selected for Baltimore Mayor Sheila Dixon's criminal theft trial will begin work Thursday morning, but first a judge will weigh new allegations involving another batch of gift cards said to have been donated by a developer not previously named in the case.

Two city developers, Patrick Turner and Ronald H. Lipscomb, have been identified as potential witnesses in the mayor's theft case, and a defense motion filed Tuesday reveals that prosecutors want a third developer to testify. The mayor is accused of buying personal items with at least $1,500 in retail gift cards donated to her office for use by needy families.

The newly named developer, Glenn Charlow, donated gift cards to Dixon to be used "in connection with her church activities," according to papers filed in court by the mayor's lawyers in an effort to block his testimony. There are no details about how State Prosecutor Robert A. Rohrbaugh believes the gift cards were used, or how much money may have been involved.

Dixon's attorneys object to the anticipated new testimony because, they say, prosecutors interviewed Charlow in June 2008 but did not disclose key information until Friday, on the eve of the trial.
