Several jurors seemed intent on making sure they understood the chaotic conversations on the audio. The jurors closed their eyes and leaned forward toward the speakers.
The jury also asked to take with them into the jury room a large aerial photograph of the scene around Tepper's home on Elkhart Street, between Thompson and Edgemont Streets.
Tepper is charged with murder and related counts in the slaying of Panas following the melee involving some guests from Tepper's baby shower for a daughter and young men from the neighborhood.
Defense attorney Fortunato "Fred" Perri Jr. argued that Tepper shot in self-defense after being jumped and punched in the face by a group involved in the melee.
But Assistant District Attorney Michael Barry urged the jury to find Tepper guilty of first-degree murder - a premeditated, malicious killing - saying Tepper was not seriously hurt and shot Panas because he mocked Tepper, saying the officer would not shot the pistol he was pointing.
As trial witnesses described the late-night incident, Panas was not among the people who jumped Tepper and hit him in the mouth. Panas and friends, witnesses said, came from the opposition direction, curious about the noisy, nearby melee.
But after they arrived, witnesses testified, Panas and several others got involved in the ongoing fistfights until Tepper drew his personal semiautomatic pistol and ordered them to back away.
When Panas responded with a dare, Tepper shot him in the chest, killing him.
