Which abbreviation is used to indicate clothing information in a dispatch report?

The abbreviation "Last seen wearing" is the correct choice for indicating clothing information in a dispatch report. This phrase provides crucial information regarding the clothing items worn by an individual at the time they were last seen, which can be vital for identification and assistance in locating the person.

Offering a clear description of what someone was wearing aids law enforcement and search teams, as it narrows down the search criteria and helps witnesses recognize the individual more easily.

Other options do not directly pertain to clothing information. For instance, "Last seen" refers to the person’s last appearance but lacks specific details about their attire. "Last spoken" pertains to any communication made by the individual and is unrelated to visual identification. "Location secured" indicates the status of a place but does not provide any clothing details. Thus, "Last seen wearing" is the most informative choice, encapsulating essential details about an individual's appearance that are necessary during searches or investigations.
