The family of the late Botham Jean is in Dallas for a summit about race, unity and leadership.
The initiative is being held in honour of the deceased, local news reports say.
The summit, which began Wednesday, will conclude on Saturday.
“It really shows what an inspiration he was in his lifetime and the impact he had on people,” Botham’s mother, Allison Jean, was quoted by NBCDFW as saying.
“In his life he created an impact. And in his death he has created an even greater impact,” Mrs. Jean told the news channel.
The family is expected back in Saint Lucia on Saturday.
Botham Jean, who was unarmed at the time, was shot dead in his own apartment by then Dallas Police Officer, Amber Guyger.
Guyger, who was subsequently fired as a cop, claimed that she mistook the young man’s apartment for hers.
They lived in the same complex.
The killing sparked protests and widespread outrage.
Guyger was charged with murder with trial scheduled for September.
