Police would more easily be able to track the cellphones of missing people under legislation endorsed by Rhode Island's state Senate.
The Senate approved the bill Tuesday. It now moves to the House for consideration.
The legislation would require cellphone providers to give information on a phone's location if police determine the owner is in danger.
The bill was prompted by the 2007 disappearance and slaying of an 18-year-old woman in Kansas. Police attempted to find her using her phone's location, but her cellphone provider initially refused to provide information about her phone's whereabouts.
Supporters say the bill would help police find abduction victims, dead bodies or lost or injured people.
Eight states now have similar laws.
