Nicole Hanson, 24, of East Cheshire, Conn., testified this afternoon that she heard glass shattering and saw a man jump from a police station window on the night that Allen was killed.

The police say Carpio killed Allen with Allen's gun, escaped by jumping out of a third-floor window and was later captured downtown.

Hanson told jurors that she was a passenger in a car driven by her boyfriend, Nathan Fiero, which was traveling south on Service Road 7.

After hearing the sound of shattering glass, Hanson looked up, saw glass falling from the sky and watched a man pushing glass out of a window frame, she testified.

Then she saw the man climb through the window frame and hang from the ledge for a moment before dropping to the ground, she said.

"He hit the ground and instantly got right up. He began ...striding" past them, Hanson said.

Hanson testified that she saw the man go across a Route 95 overpass, then jump over a wall or a fence on the east side of Route 95.

The jury this afternoon also heard from FBI Special Agent Justin Bowers, who described how he helped apprehend Carpio on Washington Street in front of the Roger Williams University Campus.

Police Sgt. Kenneth Vinacco describes today how a battering ram was used to break down the door into the locked office where Detective Sgt. James L. Allen lay mortally wounded.

The jury spent much of this morning listening to a digital recording of police dispatchers involved in the search for Carpio right after Allen's murder.

"Out the window! Out the window!" an officer said on the recording, which the jury followed with the aid of a transcript because it was often difficult to hear.

"Does anybody know which way they ran?" a dispatcher said later in the roughly 45-minute recording.
