The two men charged with vehicular manslaughter in the deaths of eight spectators at a February street race in Accokeek had been part of the crowd minutes before the collision, sources tell ABC 7/NewsChannel 8's Brad Bell.

The sources say 21-year-old Darren Bullock and 18-year-old Tavon Taylor had been showing off for the crowd: spinning their tires and pulling circles in the street as the crowd gathered on Indian Head Highway February 16 to watch the illegal street races. The men were allegedly told leave. The sources say that was when the men decided to begin their own street race, allegedly hurtling toward the crowd at 110 mph with headlights off.

Both Bullock and Taylor face eight counts of manslaughter, as well reckless driving and racing charges. 

Prosecutors will argue at trial that both men are responsible for the deaths, even though Taylor did not strike anyone, the sources said. Bullock struck several people, killing eight.

"I'm confident that the evidence supports the indictment," said Prince George's County State's Attorney Glenn Ivey.

Investigators say they arrived at their conclusions about Bullock and Taylor based on a surveillance tape and witness accounts.

At a bond review Monday, a judge set bond for Bullock and Taylor at $200,000 and $120,000, respectively.Family and friends of the defendants showed their support in the courtroom Monday. Taylor's mother Paula maintained her son's innocence, saying, "I don't understand why these charges [were] brought against my son. My son has never done nothing wrong in his life."

"I don't know how my son goes from being a witness to being indicted," she added. "He didn't hit nobody."

"He's never been a kid that was into cars. He had a little car and he used it for what he was taught to use it for," said Taylor's aunt, Kimberly.

In arguing for bond, lawyers for both defendants asserted that their clients were not violent, nor were they flight risks. The prosecution claimed they had intentionally deceived and misled investigating officers immediately after the crash.

Taylor's lawyer, J. Wyndell Gordon, disagreed with that claim. "I do feel knowing my client, talking with the witnesses, going out to the crime scene and doing our own personal investigation, that any statement that was taken from my client that's inconsistent with what he's been telling the investigators, what's been telling all those involved in this case, was coerced."
