An item in the Oct. 29 Federal Report incorrectly reported that Assistant U.S. Attorney James W. Kerr in San Antonio, Tex., had been assassinated. Kerr survived the assassination attempt.

New help for thousands of missing children and their families is contained in the omnibus spending bill that Congress passed before it adjourned earlier this month.

The bill provides $10 million in the first year to set up a national resource center that will operate a toll-free telephone hot line to gather tips on missing children, coordinate federal, state and local efforts to find them, and provide technical help and information about new approaches to tracking down missing children.

The center also will perform regular surveys to monitor the magnitude of the problem and provide grants to public and nonprofit agencies who work on the problem.

It is estimated that between 20,000 and 50,000 cases of missing children remain unsolved in the United States. KILLED IN ACTION . . .

FBI Director William H. Webster, in a memorial service in the FBI courtyard earlier this month, paid tribute to the 26 special agents who were killed in the line of duty since the bureau was created in 1908.

In the first half of 1984, Webster said, 35 federal, state and local law enforcement officers were murdered in the line of duty in the United States and U.S. territories. During that period last year, 45 were killed. TAWARD WINNERS . . .

The Association of Federal Investigators, a group of law enforcement agents from more than 60 federal agencies, will present its annual awards at its convention here Nov. 16-17. Among the recipients are:
