An undercover officer who had been inside the club testified Tuesday that he did not hear the other officers identify themselves in the moments before Sean Bell was gunned down in a hail of some 50 shots.

The New York Post said officer Hispolito Sanchez's testimony contradicted his grand jury testimony in which he said he thought he heard the commands.

Sanchez was not a member of the team that confronted Bell and had to call 911 on his cell phone to report the shooting.

Another witness, Lt. Michael Wheeler, was one of the first officers on the scene and testified that two of the three defendants, detectives Michael Oliver and Gescard Isnora, told him they did not remember how many shots each had fired.

Bell was at the strip club for his bachelor party and was shot after his car allegedly struck the vehicle the undercover team was using.
