Missing persons: mobile telephone location.

Existing law declares it the duty of all law enforcement agencies to immediately assist any person who is attempting to make a report of a missing person or runaway. This bill would authorize a peace officer to require a mobile telephony service carrier to provide the location of a mobile communication device, with a global positioning system, where the subscriber for the mobile telephony service has authorized the carrier to provide the requested information to a peace officer, where a missing person report has been filed for an at risk child or elder. Existing law requires a mobile telephony service carrier to provide subscribers with specified services. This bill would require a mobile telephony service carrier to provide subscribers with the option of authorizing the carrier to provide the location of a mobile communication device, with a global positioning system, on the subscriber's calling plan to a peace officer requesting the information, as prescribed.
