"I hope you got what you wanted," wrote another. One tweet accused her of having "snitched."
The local newspaper, The Register Citizen, archived images of tweets before many were taken down.
"Even if it was all his fault, what was a 13 year old girl doing hanging around with 18 year old guys," tweeted one girl, whose Twitter handle seemed to no longer be active Thursday. She later tweeted that she was misunderstood.
One boy tweeted that he is the cousin of the girl who wrote that tweet, and that some people on Twitter were "threatening to kill" her for what she wrote.
Brown, Gonzalez's attorney, said his client had no knowledge of the Twitter traffic, has had no access to computers and has had no visitors who could have informed him.
"I find it interesting that the accused's name is published but not the accuser's," Brown said. "But that's the law, and I have every intention of respecting and obeying the law, and my client has every intention of respecting and obeying the law as well.
"He's more concerned with moving forward with the trial, being exonerated and putting this behind him," Brown said.
