Day Two: Police assumed a revolver was used

The warrant for an open container that was out for Ishmael Rivera on Officer Lindsey's computer screen is asked of Officer Nitti. On the screen it said "arrest." Nitti says this means Rivera COULD have been taken to jail because the warrant was out.

Defense asks if Nitti is familiar with the 1100 block of Neilson Street. He says he has driven down it before. Defense asks if this is "not a quiet street," and Nitti replies "correct."

The .9 mm recovered from 1121 Neilson Street, Nitti said, told him that based on trajectory, that it could have been shot from the area where Officer Lindsey was shot. Defense asks if at the time it seemed significant; Nitti said no, not at the time, it just was the correct trajectory.

Nitti says he is aware that the call was of "multiple shots fired," that night, and says that if multiple shots were fired, they would expect to find casings.

Defense asks if casings can be retrieved, Nitti says "yes," agreeing that they're not "microscopic or too hot to handle," as defense asks.

Defense asks if it's possible for the casings to be expelled into the vehicle, and not necessarily end up on the ground. Nitti says that's possible.

When asked if they found any other places where a bullet might have hit, Nitti says yes, at 1123 Neilson Street.

Defense asks if the .9 mm found in 1121 was ruled out as relevant becuase there were no casings found at the scene on Neilson Street. Nitti says "yes."

Nitti then says that there is a difference between how far a casing can travel outside a gun when fired, versus how far a shell can travel outside a gun when fired.

Nitti then repeats that they found no shell casings in the area they would expect to find, which suggested to him that the gun used was a revolver.
