August 21 (Court TV) -- David Kaczynski, who helped reveal his brother as the Unabomber, was given a $1 million reward Thursday by the Justice Department for his efforts.

As Kaczynski was receiving his money, a federal appeals court ruled that a psychiatric report on his brother Theodore could be made public.

David Kaczynski has pledged not to keep the money, and will give it to the families of Unabom victims.

Theodore Kaczynski's mail and package bomb attacks killed three people over the course of nearly two decades and injured 29 others in incidents that stretched from New Jersey to Sacramento, California. He pleaded guilty January 22 to thirteen counts for bombing and murder.

David Kaczynski, by contrast, has served as a sort of liaison between the Kaczynski family -- from which Theodore was estranged -- and the families of the Unabom victims. At Theodore's sentencing this past May, David Kaczynski publicly apologized to the victims and their families, citing them for their "remarkable courage."

The Unabomber is being held at the Supermax federal prison in Florence, Colorado, where he is serving several consecutive life sentences.

His plea deal with the Justice Department in January spared his life, but guaranteed he would spend the rest of his life behind bars. David Kaczynski fought to save his brother's life, and reportedly asked prosecutors to try and reach an acceptable deal.

A Justice Department spokesman called the Kaczynski reward "one of the largest, if not the largest, rewards in history" and said that a $1 million check had been turned over to Anthony Bisceglie, David Kaczynski's attorney.

It was Bisceglie who helped negotiate with federal investigators for David Kaczynski's cooperation in tracking down his brother. Theodore Kaczynski was arrested in his rural Montana cabin in April 1996.

The reward is apparently taxable, and David Kaczynski may seek to set up a trust fund to help reduce the tax burden and distribute the money.

"There's no question the money could never compensate for the loss of a loved one," he told the Associated Press.

While he will not profit at all from the money, reports said he may need to use some to help pay his legal bills.

Meanwhile, the Ninth Circuit Court of Appeals in San Francisco ruled Thursday that the psychiatric report prepared on Theodore Kaczynski should be made public in order to provide a better understanding of the Unabomber's motivations.

They rejected defense attorney Quin Denvir's arguments that making the report public would violate his client's rights.

Dr. Sally Johnson, the chief psychiatrist at the federal prison in Butner, N.C. and the woman who found attempted Reagan assassin John Hinckley competent to stand trial, spent a week this January evaluating Theodore Kaczynski.

She ultimately reported that he was a paranoid schizophrenic, but was fully competent to stand trial, but the details of her report were kept under seal. Media organizations appealed to the court to release the report.

The report will not be immediately available. Defense lawyers have three weeks to file an appeal of the decision.

Theodore Kaczynski accepted his sentence this past May quietly, but maintained that prosecutors had lied about him. He also was reportedly in violent denial of his own mental illness.

"I ask that people reserve their judgment about me," he told the court before his sentence was handed down.
