PHOENIX (AP) -- Police say a man questioned in a string of Phoenix freeway shootings isn't the prime suspect and they are pressing ahead with leads in a case that has left the city on edge for two weeks.
Arizona Department of Public Safety spokesman Bart Graves said Saturday that the 19-year-old man detained is a person of interest, but he declined to say what led police to question him. He has been booked into jail on an unrelated marijuana possession charge.
Graves says the investigation is moving forward and authorities aren't concerned about the public growing complacent now that someone has been questioned. Police are still seeking tips, with freeway message boards continuing to flash a tip line number.
People who answered phones registered to the man's address said they weren't related to him.
