Friends say 34-year-old Imer Alvarado was a gay man who occasionally dressed in women's clothes.
Security footage showed a scuffle between Alvarado and Derrick Garcia in May 2017 before Garcia fired a gun.
Alvarado fell to the ground and several cars passed by without stopping to help.
Police arrested the suspect a year later.
Garcia was initially found mentally incompetent to stand trial.
His competency was restored and in May he pleaded no contest to second degree murder with a gun.
