Story highlights Sherri Papini, 34, went missing after going for a jog last Wednesday

Her iPhone, a pair of earbuds and a few strands of what's believed to be her hair were found near her home

(CNN) An iPhone, a pair of earbuds and a few strands from what's believed to be Sherri Papini's hair were found along a northern California jogging path.
