Sunday marked the eighth day since a New York teenager vanished while on spring break in Myrtle Beach, and the questions into her disappearance are mounting.

On Sunday, Myrtle Beach detectives again scoured an area in Georgetown County near the North Santee River after learning the missing teen's cell phone gave off a signal there the night she went missing.

But as has been the case since searching began there early last week, investigators did not find anything helpful.

Brittanee Drexel, 17, of Rochester, N.Y., was last seen leaving the Blue Water Resort around 8:45 p.m. on April 25, but no one has heard from her since.

The teen was leaving the hotel room of a Rochester friend and was heading back to her hotel, the Bar Harbor Hotel, according to police.

Investigators learned Brittanee's cell phone was beaming a signal to a cell tower in southern Georgetown County the night she went missing and into early Sunday morning. However, there has been no activity from it since then.

Myrtle Beach police say they continue to follow other leads and are reiterating their needs for the help of the public.

In a release Sunday morning, police urged anyone to come forward who may have seen Brittanee talking to anyone on Ocean Boulevard or getting into a car Saturday night.

Brittanee is described as a 4'11" white female with blonde hair.
