A thorough forensic examination of the computer was carried out but disallowed in court:
Horner's analysis of Amero's hard drive cast doubt on Lounsbury's conclusions. Horner found that the computer had been infected with malware before she arrived.
“She was set up days or weeks before she ever sat down,” Horton said.
Here are just a few of the red flags Horton discovered in course of his laborious forensic reconstruction: Anti-virus software triggered security alerts as soon as he started copying the hard disk for testing. The computer’s Norton activity log showed that by the time Amero came to Kelly, her computer was already infected with spyware from notorious websites including marketscore.com and new.net.
One piece of spyware had been already been tracking the computer for about a month.
Horner also discovered that someone, presumably the computer’s regular user, had been accessing eHarmony.com before Amero’s visit. As he noted, dating sites are notorious for spreading porn-related adware.
Another program called Pasco showed that malware had automatically redirected Amero’s browser. Horner stressed that this particular form of hijacking is invisible to ComputerCOP Pro.
On Oct. 19, someone did an online job search shortly after 8:00 a.m., activating several different malware apps. At approximately 8:15 a.m., someone accessed www.hair-styles.org, Horner suspects student involvement, in part because the next visit was to Crayola’s homepage. Over the next several minutes, still more malware came alive, most likely triggered by the hair site.
The user kept surfing, and by this point, “crap was pouring into the computer at the speed of electricity,” Horner said. The real point of no return was when the computer received a huge porn-filled Java file. From that point on, the machine was locked in an endless porn loop.
Note that Amero’s class started around 9 a.m. Neither the prosecutor nor detective Lounsbury was able to tell AlterNet whether the room had been locked before class, or exactly what time Amero sat down at her desk.
At trial, it emerged that the school IT department offered no protection against obscene content or invasive software. The Kelly Middle School’s firewall license had expired, leaving the whole system unguarded. To make matters worse, Amero was working on a very old Gateway PC running Windows 98, an extremely vulnerable setup.
“Anyone could send anything they wanted to any computer on the site,” Horner said.
In the course of his investigation, Horner became convinced of Amero’s innocence. After she was convicted, he sent a letter to her attorney offering his services pro bono for her upcoming appeal.
“This whole trial was so unfair,” Horner said. “When Julie was convicted, I went home that night. I was eating dinner, and I started crying. I just cried my eyes out. This was a total travesty of justice.”
