(AP) - A prosecutor has told jurors that former Dallas police officer Amber Guyger was careless and distracted when she entered her neighbor's apartment and fatally shot him.

Guyger's trial began Monday for the September 2018 fatal shooting of Botham Jean, who went by the nickname "Bo." The court didn't release demographic details about the jurors, the vast majority of whom appeared to be women and people of color.

Dallas County assistant district attorney Jason Hermus called Jean "a wonderful, decent, kind man" and said that he was eating a bowl of vanilla ice cream when Guyger entered his apartment.

Hermus told jurors that Guyger had worked a long day but that it was primarily office work. He suggested that Guyger became upset and distracted by a phone call with a colleague with whom she had been romantically involved. He said there is no evidence that Jean ever posed a threat to Guyger.

Guyger's attorney will present an opening statement later Monday.
