An attorney for the family of a man shot dead by a police officer in the man's own apartment said a police affidavit shows investigators immediately sought evidence to discredit the victim. 

The Kaufman County Jail released video Thursday of Dallas Police Officer Amber Guyger getting booked on a manslaughter charge after turning herself in on Sunday, September 9. 

Dozens of demonstrators gathered outside Dallas police headquarters Monday evening to demand justice for Botham Jean, the 26-year-old who was shot inside his own apartment last Thursday by off-duty police officer Amber Guyger. 

The case against a white Dallas police officer who shot and killed a black neighbor in his home will be presented to a grand jury, which could decide on more serious charges than manslaughter, the district attorney overseeing the case said Monday.
