The reward for information leading to missing New York teenager Brittanee Drexel was increased to $11,000, the Rochester Democrat and Chronicle reported.
Pastor Charlie Muller, of Victory Christian Church in Albany, N.Y., added $10,000 to the $1,000 reward Myrtle Beach, S.C. Crime Stoppers offered last week, the newspaper reported.
The Rochester, N.Y. teen on spring break in Myrtle Beach, was reported missing two weeks ago.
At about 8 p.m. on April 25, Brittanee left the Bar Harbor Hotel, where she was staying with some girl friends, and headed to the nearby Blue Resort Hotel to see friend Peter Broswick.
Surveillance camera footage captured 17-year-old Brittanee entering and leaving the Blue Resort lobby.
Hours later, at about 1 a.m., Broswick left Myrtle Beach to return home to Rochester. Authorities there and in Myrtle Beach have questioned him several times, but say he isn't a suspect.
Detectives believe Broswick may have been the last person to see Brittanee, a student at Gates-Chili High School in Rochester, alive.
Dawn Drexel has said her daughter suffers from depression and may have been upset because she and her husband are getting divorced. But she insists the girl would never run away.
Brittanee has blue eyes and shoulder-length brown hair with blond highlights. She's 5 feet tall, weighs about 100 pounds and was last seen wearing a multi-colored shirt, black shorts and flip-flops.
Those with any information are asked to call Myrtle Beach Police at (843) 918-1300, 1-800-CRIME-TV or 1-800-THE-LOST (843-5678).
