An Afghan judge sentenced four men to death for the mob killing of the woman, named Farkhunda, on March 19 in Kabul.
The trial of 49 men, including several policemen, accused of involvement in the killing began in Afghanistan four days ago.
19 police defendants were accused of failing to stop the attack and neglecting their duties.
Judge Safiullah Mujadidi has announced the sentences of each defendant one by one. He has given death sentences to four men and 16 years in jail to eight others for charges of assault, murder and encouraging others to participate in the assault.
18 were released due to a lack of evidence.
The remaining 19, all of them police officers, will be sentenced on Saturday. The defendants have the right to appeal.
The twenty seven-year-old woman was accused of burning a Quran and beaten to death in central Kabul as police allegedly looked on. The murder sparked several unprecedented protests in Kabul and other major cities of Afghanistan.
