Nixle offers law enforcement agencies a secure, real-time, hyper-local communications technology to issue Silver Alerts-public notifications specific to locating missing seniors with Alzheimer's, dementia and other mental disabilities. Used by law enforcement in 24 states, Silver Alerts drive community search and rescue efforts. Nixle distribution of Silver Alerts is free to all law enforcement agencies. Nixle enables law enforcement to direct instant hyper-local Silver Alerts with photos of the missing to a broad or narrow radius of residents in proximity to the incident. Nlets provides the secure national law enforcement infrastructure and uncompromised network that allows Nixle to safely deliver these alerts. Nlets also facilitates electronic messaging among state, local, and federal agencies-which can provide crucial additional help in the event the search goes beyond the missing person's immediate community. When used to distribute Silver Alerts, Nixle has yielded numerous positive outcomes. Nixle's service was deemed essential in the search and rescue of an 84 year old Alzheimer's patient in Denton, Fla. The local police department issued a Silver Alert through Nixle to residents in the immediate vicinity. A neighbor and Nixle subscriber received the alert on his phone and by e-mail. Shortly after, he came across the lost adult a few miles from his home and contacted the police. The patient was rescued. Nixle is also used to distribute Amber Alerts to find missing children and for Blue Alerts, which broadcast information about violent criminals on the run.
