Which description corresponds to code 403?

• A. Unknown Trouble
• B. 9-1-1 Disconnect
• C. Prowler
• D. Suicide

Answer: (C)

Code numbers map to specific on-scene descriptions to guide how units respond. For 403, the description that fits is a prowler—the report of a person seen lurking around property or attempting to gain entry, typically someone present but not yet engaged in an active burglary. This signals a suspicious presence that requires cautious, perimeter-oriented response and rapid assessment of intent and risk.

Other options describe different situations: unknown trouble is a vague or unclear report, not the precise alert described by 403; a 9-1-1 disconnect refers to a call where the caller disconnected, and suicide indicates a separate crisis that follows its own protocol.
