Neighbors and activists gathered at Leimert Park in downtown L.A. to honor Trayvon Martin on the one year anniversary of his death on Tuesday.

About 60 people attended the gathering, and many held signs with Martin’s picture. Some wore hoodies in remembrance of his attire when he was killed, and others held up a bag of Skittles – what Martin was holding during his confrontation with George Zimmerman, the neighborhood watchman who has been accused of killing Martin. Zimmerman’s trial is set to begin in June.

Olivia Anderson, mother of two boys, attended the event to help spread awareness of Martin’s case and ongoing racial tensions in America. People often do not care until it is their child who is killed and then they become involved, she said.

Speakers held a press conference to comment on Martin’s death and shared personal stories of loved ones lost.

Genevieve Huizar, a speaker at the event, talked about her son Manuel Diaz, who was shot by an Anaheim police officer last July.

“This is very difficult for any mother to have to go through and we don’t want this to happen to any families. We want these killings to stop,” Huizar said.

Ilsie Dixon, a neighbor who attended the event, lost her son in a shooting seven years ago.

“Nothing is going to bring this kid back,” she said. “I want to give that mother support. I know how she feels.”
