The Johnson County Central Dispatch is warning residents of a 911 texting scam. Callers report they’ve received a text message telling them to call 911. Authorities believe some type of virus on social networking sites is pulling people’s information and sending the text messages. If you receive a text telling you to call 911, it is not a real text. For more information or to report an incident contact the Johnson County Central Dispatch at (660) 747-5511.
