A community in Palmdale, California is searching for answers after the suspicious death of a 24-year-old Black man.

According to CNN, Robert L. Fuller was found hanging from a tree around 3:30 a.m. on Monday near Palmdale City Hall. Fire fighters and law enforcement responded to the scene after a passerby spotted the 24-year-old.

Investigators are describing the tragedy as "an alleged death by suicide."

"Sadly, it is not the first such incident since the COVID-19 pandemic began," city officials said in a statement. "The city remains committed to addressing mental health issues during these difficult times. We are in this together."

Mayor Steven D. Hofbauer tried to calm the angry residents who attended the press conference on Friday, according to The Daily Beast.

"We're working hard to try to figure out exactly what happened," Hofbauer said. 

The community demanded to see footage of the incident, but city officials said there isn't any available. Although there are no cameras around City Hall, investigators are looking at footage from businesses in the area, The Daily Beast reported. 

Hofbauer said the city is working with the sheriff's department, the coroner's offices and other investigative agencies to look into the matter.

"We are awaiting all available details surrounding this tragedy," the mayor said. "In addition, we are working with local community leaders to increase the dialogue on how we can best work together and build a safer and more inclusive community."

Investigators said they didn't find any "signs of a struggle” and Fuller died by suicide. 

“Many people are suffering extreme mental anguish and the City wants everyone to know that help is available,” City Manager J.J. Murphy said in a statement. 

Still, the community has questions.  

“Remember what the first coroner said about George Floyd?” one woman at the press conference shouted, noting how the initial report in Floyd's case didn't rule his death as a homicide.

Other residents at the press conference noted Fuller was recently marching in a Black Lives Matter protest. 

Lt. Brandon Dean from the Los Angeles County Sheriff’s Department Homicide Bureau said investigators are “not officially saying that this is a suicide,” The Daily Beast reported.

Dean said there was “nothing that would indicate he was put up there against his will.” 

“The rope wasn’t thrown over but tied to the branch, which means somebody had to get up there and tie it,” the lieutenant told The Daily Beast. 

Now, investigators are waiting for the toxicology results.

“If the toxicology results were to show a high level of a chemical that might have poisoned him or knocked him unconscious and allowed someone to drag him up there, it would give a new direction to the case,” Dean said. 

One woman, identifying herself as Abby, called into a local radio show on Friday and described herself as a friend of Fuller. 

“If you knew this young man, you would never get the thought of him having some type of mental illness. He was always smiling,” she said. "They’re trying to cover it up as a suicide and it’s not a suicide.”

The community has created a petition, demanding "the Los Angeles Sheriff’s Department Palmdale Station and the City of Palmdale to conduct a full, thorough investigation into Robert’s death."

"During such a heightened time with the Black Lives Matter movement and the city’s quickness to call his death a suicide before any investigation, there is reason to believe that Robert’s death was a lynching," the petition stated.

Advocates also said there is a history of racism in the community. 

"Palmdale and the Antelope Valley as a whole have a history of racism and negligence," they wrote. "This is the same town where 8-year-old Gabriel Fernandez was murdered. The city’s law enforcement and social workers failed to intervene to save his life." 

The sheriff's department said it has already made contact with Fuller's family and "a full autopsy is expected to be conducted in the immediate future."
