Yesterday morning, a photograph of New Haven police Sgt. Dario “Scott” Aponte was added to a memorial at department headquarters. Aponte’s family and more than 50 New Haven police officers and staff were in attendance. Aponte’s photo joined the photos of 19 other New Haven police offers who have been killed in the line of duty. Aponte was killed when his car collided at high speed with another police cruiser on Sept. 9. The officer driving the other car, Diane Gonzalez, is still in intensive care at an area hospital as a result of her injuries from the crash. Both cars were responding to the same domestic violence call.
