Testimony concluded in the Sean Bell case with the last of the six defense witnesses taking the stand on Tuesday, the 26th day of the trial, and both sides preparing to deliver closing arguments next week, lawyers said.

The defense did not formally rest its case. But it is expected to so on Thursday after making various motions before Justice Arthur J. Cooperman, who is hearing the case without a jury. After closing arguments, the judge will consider verdicts in the charges against the three defendants, Detectives Gescard F. Isnora, Michael Oliver and Marc Cooper. Detectives Isnora and Oliver face charges of first- and second-degree manslaughter, assault and misdemeanor counts of reckless endangerment. Detective Cooper, whose shots hit no one, faces just the charges of reckless endangerment.

The detectives did not testify, indicating that their lawyers were satisfied with the versions of the shooting that the men gave under oath in grand jury testimony last year, accounts that were read aloud by prosecutors during the trial. By putting the detectives on the witness stand, the defense would have given prosecutors the chance to trip them up on cross-examination, an opportunity that prosecutors did not have in reading back the old testimony.

The defense case lasted three days. Its star witness was its first, Officer Michael Carey, who fired 3 of 50 shots in the shooting on Nov. 25, 2006, outside the Club Kalua in Jamaica, Queens, that killed Mr. Bell and wounded two of his friends, Trent Benefield and Joseph Guzman.
