The Latest on the homicide trial of a white Pennsylvania police officer in the shooting of an unarmed black 17-year-old (all times local):

10:30 p.m.

The district attorney in Pittsburgh says he disagrees with a jury's decision to acquit a former police officer in the fatal shooting of an unarmed black teenager as he ran from a car involved just minutes earlier in a drive-by shooting.

But Stephen Zappala Jr. says it is the people of Pennsylvania who decide guilt in criminal cases, and "they have spoken."

A jury deliberated fewer than four hours Friday before clearing ex-East Pittsburgh Officer Michael Rosfeld of homicide in the shooting of Antwon Rose II last year.

Rosfeld's lawyer called him "a good man." During the trial he said the officer feared for his life and had to make a split-second decision.

Zappala said that in the interest of justice, he'll continue to bring charges where charges are appropriate.

The family of a black teenager who was shot in the back and killed by a white police officer outside Pittsburgh remained stoic after the man was acquitted.

Antwon Rose II's sister had tears streaming down her face after the jury cleared former East Pittsburgh Police Officer Michael Rosfeld of a homicide charge late Friday. Her mother urged her not to cry.

The jury deliberated fewer than four hours before reaching its verdict. There were tears and gasps from black people gathered in an overflow courtroom, and several broke out in song: "Antwon Rose was a freedom fighter, and he taught us how to fight."

Rosfeld's wife burst out sobbing as the verdict was announced. She and Rosfeld were hustled out of the courtroom by deputies.

Rosfeld's attorney, Patrick Thomassey, told reporters that Rosfeld is "a good man."

An expert in police use of force says a former officer did everything by the book in a fatal encounter with an unarmed black teenager outside Pittsburgh last summer.

Retired Pennsylvania State Police Trooper Clifford W. Jobe Jr. testified for the defense at the homicide trial of former East Pittsburgh Police Officer Michael Rosfeld, who's charged with gunning down 17-year-old Antwon Rose II.

Rosfeld fired three bullets into Rose after pulling over an unlicensed taxi that had been used in a drive-by shooting. Rose, a passenger in the car, was shot in the back as he fled.

Jobe told jurors Thursday that Rosfeld followed proper procedure. Prosecutors say Rosfeld gave inconsistent statements about the shooting, including whether he thought Rose had a gun.

The trial resumes Friday with Jobe back on the stand for cross-examination.
