DETROIT -- The Wayne County Prosecutor announced Monday that the charges against the man suspected of shooting nine people at Hart Plaza were dropped.

Prosecutor Kym Worthy said Monday that forensic evidence failed to link Daron Caldwell, 32, to the shooting scene.

"This action was precipitated by receiving forensic evidence in the late evening of Oct. 1, 2004, that Mr. Caldwell's DNA failed to match any of the physical evidence found at the scene of the shooting," Worthy said.

Caldwell (pictured, left) has maintained his innocence since his arrest in June, Local 4 reported.

"It was overwhelming. It's been a lot on me from day one … They made me look like a menace to society," Caldwell said after his release on Monday.

In spite of Monday's announcement, Detroit police Chief Ella Bully-Cummings and Worthy said that Caldwell could face future charges.

Worthy said Caldwell declined to take a polygraph test upon his arrest. She added that the evidence still points to Caldwell, but there's not enough to prove he is guilty beyond a reasonable doubt.

"While this evidence does not eliminate Mr. Caldwell's participation in the shootings, or his known presence at the crime scene, we cannot proceed with the prosecution of this case at this time," Worthy said. "Please be clear that we do not think we erred in any way, shape, form or fashion in charging Mr. Caldwell."

Caldwell was the prime suspect in the June 23 incident at the International Freedom Festival, where nine people were shot.

The shooting occurred at Woodward and Jefferson, near the Joe Louis Fist statue, just as the fireworks display began shortly after 10 p.m., according to Local 4 reports. Officers from the Detroit Police Violent Crimes Task Force arrested Caldwell at a barber shop on Dexter and Tyler streets on the city's west side at about 6 p.m. the next day.

Timeline: People Vs. Daron Caldwell

Caldwell was charged with second-degree murder after one of the victims -- 48-year-old Donald Murphy -- died of complications from his wound. Caldwell also faced six counts of assault with intent to murder, felon in possession, felony firearm and habitual second offender charges, according to the prosecutor's office.

Within hours of the shooting on June 23, police said three people identified him as the shooter, but at a preliminary examination on a later date, most witnesses could not place him at the scene, the station reported.

Caldwell's supporters claimed that he was at the Shorecrest Motor Inn hotel when the shooting took place.

"There was plenty of eyewitnesses that seen him watch the fireworks on television," said one woman.

Murphy's twin brother, Ronald, told Local 4 that with Caldwell's release, he lost the closure he and his family had in feeling that his brother's killer was in custody.

"We're back to square one. Someone is still out on the streets that they got to look for," he said.

Worthy said Monday that there is new evidence that suggests a second gun may have been used in the shootings.

"The fired evidence suggests that there was more than one weapon used in this particular case," she said.

The evidence was taken from a bullet recovered from one of the shooting victims, Local 4 reported.

Police continue their search for 24-year-old Gary Williams (pictured, right), who investigators initially believed may have been connected to the shooting.

Caldwell, Supporters Maintained His Innocence

Monday's announcement left a sigh of relief for Daron Caldwell, and his family and friends.

Caldwell and his supporters have maintained his innocence since the accusations began, with some wearing T-shirts stating "Not Guilty" during his court appearances.

His attorney said Monday that he is grateful the community rallied behind him, pressuring law enforcement to come to the right conclusion.

"He said it has been a living hell back there," Caldwell attorney Marlon Evans said about his client. "He said it is one thing to be locked up for something you know you are responsible for, it's another thing to be locked up for something that you know you didn't do."

Caldwell's mother, Blanche Thomas, said she feels wonderful "after feeling so terrible for months on end. Not sleeping. Not eating. I am good."
