A report on the emergency response to last year's shooting at Los Angeles International Airport cites serious shortcomings in communication between agencies that left major commanders in the dark and a long lag in establishing a coordinated response.

An early copy of the report to be presented to airport commissioners Tuesday was obtained by The Associated Press.

It cites the "heroism" of officers who shot and took suspect Paul Ciancia into custody after he'd killed a Transportation Security Administration officer and injured three people Nov. 1.

But it details lapses in coordination and technology between police and fire departments, which set up separate command posts that didn't unify for 45 minutes.

The report says police and fire commanders arrived on the scene with no idea where to go or what the others were doing.
