( CNN ) -- Police are examining grainy hotel surveillance video and following up on new leads , including a reported sighting , in the case of a 17-year-old girl who traveled to Myrtle Beach , South Carolina , for spring break last week and then disappeared . Brittanee Marie Drexel 's mother says she thought her daughter was at a beach in New York , not South Carolina . The possible sighting of Brittanee Drexel was on a bus Wednesday morning in the Myrtle Beach area , according to police , who later showed photos of her to passengers . As investigators try to build a timeline of the events leading to Brittanee 's disappearance Saturday night , they are also scrutinizing hotel security video for signs of a young woman in distress , or other clues . Brittanee 's mother , Dawn Drexel , told HLN 's Nancy Grace that she had forbidden the Rochester , New York , high school junior from going to Myrtle Beach , a popular destination for high school and college students on spring break . Although they stayed in touch by phone and spoke on Saturday , Drexel said she believed the girl was in Rochester when she actually was in Myrtle Beach . `` I did n't have any idea that she was going to do this , '' Drexel said . `` I do trust my daughter , and she needed to cool down a little bit because she was upset that I was n't going to let her go . '' Drexel said her daughter rode there in a car with several friends . She thinks Brittanee used money she had earned and borrowed to finance her trip .
