Abstract

Wireless devices are often associated with security events. The security events may be investigated by identifying and locating the associated wireless devices by: 1) determining a time and a location of a security event; 2) accessing a first wireless network and determining at least one of an ID and a location for at least a first wireless device within a predetermined proximity of the security event; and 3) determining at least one of an ID and a location for a second wireless device that was in communication with the first wireless device within at least one of: a predetermined span of time prior to or concurrent with the time of the security event, and a predetermined proximity to the security event.

Claims

1. A method for identifying and locating wireless devices associated with a security event comprising:

determining a time and a location of a security event; and

accessing a first wireless network and determining at least one of an ID and a location for at least a first wireless device within a predetermined proximity of the security event;

wherein the security event is an explosion or gunshot.

2. The method of claim 1 further comprising:

determining at least one of an ID and a location for a second wireless device that was in communication with the first wireless device within at least one of;

a predetermined span of time prior to or concurrent with the time of the security event, and a predetermined proximity to the security event.

3. The method of claim 1 wherein the wireless network is commercial communications network.

4. The method of claim 3 wherein the commercial communications network is a cell phone network.

5. The method of claim 3 wherein the commercial communications network is a pager network.
