MADISON, Wis. (AP) -- Police would be prohibited from tracking cellphone locations without a warrant under a bill headed to Gov. Scott Walker.
The Senate passed the measure on Tuesday on a voice vote. The Assembly approved it last week.
Under the bill, police would have to submit details about their investigation in the application for a warrant to track a cellphone.
That information would include the subject of the investigation, a statement of the crime and a statement of probable cause to believe there is criminal activity. Police would also have to decide how tracking the phone would yield relevant information.
