BROOKLYN - A judge today declared a mistrial in the Tiana Browne murder case because a prosecutor withheld information about a witness.

The judge says prosecutors didn't disclose that Marva Braithwaite, the mother of the teen allegedly killed by Browne, had a prior felony charge. The judge says Braithwaite provided a significant amount of testimony during the trial.

Browne, 17, was accused of killing her 16-year-old cousin - Braithwaite's daughter - two years ago in Crown Heights.

The judge would like a new trial started quickly, but witnesses need to be flown back into New York and a new jury needs to be chosen, which is expected to delay the proceedings.
