Chief Burke, in an interview last week, said the caller gave a complete description of the gun.

One caller gave the police the exact license plate number.

Before hanging up, her caller gave her a new set of instructions.

The caller gave the name of a guard at a White House gate.

The caller then gives a phone number so that other listeners can contact the person for further information.

The phone call came in and the caller wouldn't give her name.

The caller gave me a listing of all night restaurants.

The 911 operator answered and the caller would not give his name.

Long-distance callers give their medical history, then speak for 20 minutes with a doctor.

Officials said part of the confusion was caused by the incorrect address the caller initially gave to 911.
