LaWanda Clark told jurors Wednesday during Guyger's murder trial that she struggled with a crack cocaine addiction and that Guyger wrote her a ticket on the day of the drug bust. She says Guyger told her that the ticket could be the impetus to turn her life around.

While Clark was speaking, attorneys showed jurors a photo of Guyger attending Clark's graduation from a community drug treatment program.

Clark said Guyger treated her as a person, not as "an addict," and said she is now sober.

Guyger faces up to life in prison for the September 2018 shooting death of Botham Jean. She says she mistook Jean's apartment for her own, which was one floor below.

A high school friend who played in an all-female mariachi band with Amber Guyger says the former Dallas police officer feels "immense remorse" for fatally shooting a neighbor in his own apartment.

Maribel Chavez testified Wednesday that she met Guyger in ninth grade during orchestra practice. They later went on to play in a mariachi band, with Guyger playing violin and trumpet.

Chavez said Guyger is typically bubbly and extroverted, but that since she killed her neighbor, Botham Jean, in September 2018, "It's like you shut her light off."

She described her friend as selfless, caring and a protector of those around her.
