A key witness in the Mary Lou Bigford murder trial was admonished Monday after becoming hostile with a defense attorney and threatened to walk off the stand. Jessica Perry, a downstairs neighbor of Bigford said “There was no grief, no anger, no happiness” in Bigford’s demeanor as she saw her shoot at Lawrence Howard in his parked car.
