The Daily Herald reports state law only lets a judge order GPS monitoring after a suspect has violated an order of protection - not before.
The legislation would let authorities monitor someone as soon as protective order is issued.
The bill was introduced by state Rep. Barbara Wheeler, a Crystal Lake Republican. She says she drafted the measure after the slaying of an Antioch woman who was killed by her ex-boyfriend even though she'd taken out an order of protection against the man.
The bill passed the House and now advances to the Senate.
