A court affidavit says that officer Amber Guyger shot and wounded Uvaldo Perez on May 12, 2017, after a struggle that resulted in Perez taking her Taser.

Police named Guyger on Saturday as the off-duty officer who shot and killed Botham Jean on Thursday night after she says that she mistakenly went to the wrong apartment and encountered him.

The Texas Rangers are investigating and a lawyer for Jean's family has called on authorities to arrest Guyger. Dallas police say the state police have requested more time to investigate.

In the 2017 confrontation, the affidavit says Guyger was one of two officers called to help another officer. Guyger was trying to assist, when a struggle began with Perez. Guyger fired her Taser at Perez, who then took her Taser from her. Guyger pulled her gun and fired, wounding Perez in the abdomen.

Guyger was not charged over the 2017 shooting.

A lawyer for the family of a Jean says an arrest warrant should be issued for the officer.

Dallas Police Chief U. Renee Hall had said on Friday that the officer would be charged with manslaughter but on Saturday she said a warrant had not been issued because the Texas Rangers asked her department to wait. She says the Texas Rangers wanted more time to investigate.

Botham Jean graduated Harding University in Arkansas in 2016, he had been living and working in Dallas at accounting and consulting firm PwC.

Family and friends described Jean as a devout Christian and a talented singer.
