From [HERE] and [HERE] The officer who is a target in a federal probe of the police department claimed he pushed a handcuffed prisoner because the man had spun toward him in a threatening manner and invaded his personal space.

But a review of the security tapes of the May 2010 incident involving Evan Cossette, the police chief's son, and the prisoner, Pedro Temich, shows there is about a six to eight second gap in the security tapes that could have been picked up by a camera in the booking area outside the holding cell. Police now say that tape has been erased.

The gap coincides with the time when the prisoner would have made the move that Cossette described to internal affairs investigators.

Officer Evan Cossette is seen on surveillance video pushing a handcuffed man, Pedro Temich, in a holding cell after he was picked up for intoxication in Meriden last May. In the video, Temich hits his head on a concrete bench and Evan Cossette is seen moving the unconscious Temich, but never calling for medical assistance.
