The special prosecutor assigned to oversee the investigation, Angela Corey, announced Monday that she would not present the controversial shooting case to a grand jury.
A grand jury had been scheduled to convene on April 10 in the case before Corey waved it off saying "the decision should not be considered a factor in the final determination of the case."
But some legal experts say Corey's announcement could signal an imminent decision for George Zimmerman, the man accused shooting an unarmed Florida teenager.
"I would anticipate she will move quickly on this," said Paul Callan, a former New York homicide prosecutor. "I think you'll see her come down with charges probably very, very soon."
Zimmerman's attorney, Hal Uhrig, told CNN that he was "not surprised" that Corey wouldn't present a case to a grand jury.
"Don't know what her decision will be. Courageous move on her part," he wrote in a text message to CNN's Martin Savidge Monday. Uhrig said he and Zimmerman legal adviser Craig Sonner plan to meet with Zimmerman for the first time "probably later this week."
Martin's death has triggered a nationwide debate about race in America and Florida's "stand your ground" law, which allows people to use deadly force anywhere they feel a reasonable threat of death or serious injury.
Zimmerman, a neighborhood watch volunteer, told Sanford, Florida, police the February shooting was an act of self-defense. Zimmerman has not been charged with a crime in Martin's death, a fact that has provoked demonstrations and calls that he be prosecuted for killing.
Zimmerman recently launched a website, warning supporters about groups that falsely claim to be raising funds for his defense and soliciting donations for himself.
"I am the real George Zimmerman," declares the website, set up over the weekend.
"On Sunday February 26th, I was involved in a life altering event which led me to become the subject of intense media coverage. As a result of the incident and subsequent media coverage, I have been forced to leave my home, my school, my employer, my family and ultimately, my entire life. This website's sole purpose is to ensure my supporters they are receiving my full attention without any intermediaries."
The statement posted on therealgeorgezimmerman.com warns viewers that "some persons and/or entities have been collecting funds, thinly veiled as my 'Defense Fund' or 'Legal Fund.' I cannot attest to the validity of these other websites as I have not received any funds collected, intended to support my family and I through this trying, tragic time."
But the site includes a link through which viewers can donate money to pay for Zimmerman's lawyers and living expenses "in lieu of my forced inability to maintain employment." Zimmerman pledges to "personally maintain accountability of all funds received."
"I am grateful to my friends that have come to my aid, whether publicly or personally, never questioning my integrity or actions, understanding that I cannot discuss the details of the event on February 26th, and allowing law enforcement to proceed with their investigation unhindered," the 28-year-old Zimmerman wrote on another of the site's pages. "Once again, I thank you for your patience and I assure you, the facts will come to light."
Until now, only friends and relatives have come forward to speak on Zimmerman's behalf. His attorneys have said he wants to share his story but can't, because of threats to his safety and the possibility of criminal charges.
Zimmerman's lawyers and a friend confirmed the authenticity of the website. The friend, Frank Taaffe, told CNN sister network HLN that while the site is being used to raise funds for a legal defense, it doesn't mean Zimmerman expects to be charged in connection with Martin's death.
"That has nothing to do with it," Taaffe told HLN's "Issues With Jane Velez-Mitchell."
But Benjamin Crump, a lawyer for Martin's family -- which also has a site raising funds to support their efforts -- said it's unfair that Zimmerman is still free to express his views and solicit money.
"If the situation was reversed, Trayvon Martin would have been arrested day one, hour one," Benjamin Crump told CNN's "Anderson Cooper 360" on Monday night. "We believe Zimmerman should have been arrested and put into jail. This situation with this website is a luxury that Trayvon Martin doesn't have and never would have had."
Sanford police questioned Zimmerman and released him without charges. Authorities have said Zimmerman was not immediately charged because there were no grounds, at the outset, to disprove his account that he'd acted to protect himself. But thousands have converged on Sanford to join in protests calling for Zimmerman's arrest and criticizing the police department's handling of the case.
On Monday, a group of students calling themselves the Dream Defenders marched to the Sanford police station. Six of the demonstrators wore hooded sweatshirts, as Martin did the night he was shot, as they blocked the department's main entrance; others linked arms, sang and chanted as they stood facing the building.
The demonstration closed the Police Department headquarters briefly, and City Manager Norton Bonaparte Jr. and Acting Police Chief Darren Scott met with leaders of the student group and community leaders.
Although details of the February 26 incident remain murky, what is known is that Martin, who was African-American, ventured out from his father's fiancee's home in Sanford to get a snack at a nearby convenience store. As he walked home with a bag of Skittles and an Arizona iced tea, he was shot and killed by Zimmerman, who is Hispanic, and who had called 911 to complain about a suspicious person in the neighborhood.
