"I just need you guys to turn yourself in or if whoever knows or seen anything to come forward," she said.
Hicks was stabbed on Nov. 7, 2020.
Surveillance video released by Los Angeles Sheriff's Department homicide investigators shows Hicks walking down Compton Avenue near 68th Street around noon that day wearing a white T-shirt and a cap. In the video, Hicks is seen getting into an argument with two men.

The argument lasts for a short while, then, minutes after it happened, the two suspects get into a black Toyota Prius and speed back to attack Hicks.
"[Hicks] ends up going home to his mother where he informs her he's been stabbed and she calls 911," said Lt. Derrick Alfred with LASD's homicide bureau.
Hicks died a couple of days after he was stabbed on Nov. 9. Now, it's been nearly a year and a half since the murder, and there's now a $20,000 reward for information leading to an arrest.
Investigators believe the suspects live in the neighborhood near where the incident took place. Meanwhile, Hicks' family says he leaves a great void.
When Hicks was in college a few years ago, he played college football at West L.A. College. He then transferred to Tuskegee University in Alabama to play football there.
The 31-year-old leaves behind his girlfriend and their 6-year-old daughter.
"He didn't deserve this. He was a college grad. He was a great Tuskegee football player. He loved his daughter more than anything in the world," said Hicks' girlfriend Keilah Duren.
"I'm not angry, I'm more hurt than anything. The anger has passed," said Stringer. "My son was a loving father, a devoted brother, a loving son and he did not deserve this."
Anyone with information is urged to contact the LASD's homicide bureau.
