MYRTLE BEACH, S.C. -- The mother of a New York teen who was last seen in South Carolina nearly a year ago says she's been told little about new information in the case.

New video of Brittanee Drexel, who was 17 when she was last seen in Myrtle Beach on April 25, 2009, was shown before "Today" show host Matt Lauer interviewed Dawn Drexel, the teen's mother. The video from "Investigation Discovery" shows Drexel the day before her disappearance in a hotel room and texting on her phone.

Drexel told NBC's "Today" show on Friday she thinks police in South Carolina are trying to find her daughter.

Police have indicated they think Brittanee is dead and Drexel said Friday the only real possibilities are that her daughter is being held against her will or that she is dead.

"She's either being held against her will, she's been trafficked or she's not alive," Drexel said on "Today."

Police told a WPDE-TV in Myrtle Beach last week they have identified several people of interest. The Rochester, NY, woman says that's also about all police have told her.

A vigil is planned in Myrtle Beach next week to mark the one-year anniversary of Brittanee's disappearance.
