TEXAS (WKZO) -- A woman threatening to throw herself off the top of a concrete wall over westbound I-94 near 9th street in Texas Township brought traffic on the interstate to a halt for about 20-minutes just around 3 p.m. Sunday. The 24-year-old woman from Battle Creek began negotiations with Kalamazoo County Sheriff's deputies dispatched to the scene.  They managed to talk her down and into an ambulance.
