The last cellphone ping for Emilio Acosta was detected not far from the American Dream Mall in New Jersey back on Dec. 18. Since that night, family and friends have continued their search for the missing 20-year-old Weehawken man, last leaving his home around midnight. "Not knowing that your loved one is ok is excruciating and we are so grateful for friends and family who have tried to locate him," the man's father, Ildefonso Acosta, said earlier this month.
