-- A Florida man was found guilty Friday of stealing information from data-management company Acxiom Corp. in what prosecutors said was the largest federal computer theft trial ever.

A jury convicted Scott Levine, the owner of defunct e-mail marketing contractor Snipermail.com, on 120 counts of unauthorized access to data, two counts of access device fraud and one count of obstruction of justice. Jurors cleared Levine of 13 counts of unauthorized access of a protected computer, one conspiracy count and one count of money laundering.

Statutory maximum sentences for his convictions total 640 years in prison and fines of $30.7 million, but his punishment likely will be much less under federal sentencing guidelines. Sentencing was set for Jan. 9.

Prosecutors said Levine and his company stole 1.6 billion customer records, including names, e-mail and postal addresses. The government did not charge anyone with identity theft.

Six Snipermail employees pleaded guilty to conspiracy charges and testified against Levine in the case.

"We're very pleased with the outcome," U.S. Attorney H.E. "Bud" Cummins said outside U.S. District Court. "These are very serious crimes, a huge amount of data that was stolen for monetary gain and he should be held accountable."

Levine's lawyer, David Garvin, said the verdicts were "compromised" because the jury found Levine guilty based on the same evidence jurors acquitted him on in the other counts.

Little Rock-based Acxiom, which serves large corporations by collecting and managing information for marketing purposes, said it has tightened its security since the unauthorized access was discovered two years ago.
