Jeanie Lauer Cell phone tracking bill in Mo. Gov. Nixon's hands By Marshall Griffin • May 31, 2012 (via Flickr/papalars) Among the more than 110 bills passed by Missouri lawmakers this year is one designed to help law enforcement officers track a missing person through the potential victim’s cell phone signal. If signed by Governor Jay Nixon (D), the bill would require cell phone companies to provide police with the location of any customer who’s been reported missing or believed to be in danger. The sponsor, State Rep. Jeanie Lauer (R, Blue Springs), says it’s in response to the 2007 kidnapping and murder of Kelsey Smith in the Kansas City area.
