OMAHA, Neb. - The young man who killed eight people and committed suicide in a shooting rampage at a department store spent four years in a series of treatment centers, group homes and foster care after threatening to kill his stepmother in 2002.
Finally, in August 2006, social workers, the courts and his father all agreed: It was time for Robert Hawkins to be released - nine months before he turned 19 and would have been required to leave anyway.
Under state law, Landry said, wards are released when all sides - parents, courts, social workers - agree it is time for them to go. Once Hawkins was set free, he was entirely on his own. He was no longer under state supervision, and was not released into anyone's custody.
