It's been nearly three weeks and still no sign of Joanna Rogers.
This weekend, 700 people showed up to help search for the missing Lubbock teen. Volunteers and authorities combed through a ten mile radius around the Rogers home.
"Found a lot of items of interest, of course we'll have to take them and evaluate if they have to do with this case," said Sgt. Greg Parrot with the Lubbock Sheriff's Department.
A total of $15,000 in reward money is being offered in connection with the case.
