A legislative committee in Lansing has begun work on a measure requiring cell phone companies to quickly provide location information if it's requested by police.

The bill is based on laws approved in other states.

Sponsors say it speeds up the search for missing or abducted people and has also proven to help those who have immediate medical needs.

It's called the Kelsey Smith legislation, named after a Kansas teen who was abducted and murdered in 2007.

In that case, the cell phone company did not immediately provide location information on the teen's cell phone location. The bill is before the House Criminal Justice Committee.
