It would allow law enforcement to find the location of cell phones without having to jump through current legal hoops.
State Senator Mike Parson of Bolivar handles the bill in the Senate. He says it allows police to quickly begin finding someone they're looking for.
"You have a missing person, an abducted, or involved unfortunately in a homicide, they would be able to track their phones, their cell phones, to a location where they're at," Parson says.
Currently in Missouri, cell phone companies are not allowed to give out tracking information for their customers without special clearance. The bill would allow the information to be released to police in emergency circumstances.
"There's been many times that is could be the difference between saving someone's life and not. And I think it's a very reasonable bill, and I truly believe, down the road, it will save somebody's life," Parson says.
The kidnapping incident began Tuesday in a St. Louis hospital and ended in a Chicago suburb.
