Teenage 'rape victim' is rescued from kidnap ordeal after secretly using a tracking app on her smart phone to reveal her location in Georgia

A teenager who was allegedly kidnapped and raped was rescued by police after she secretly used a tracking app on her smartphone to reveal her location in Georgia.

The 17-year-old girl was allegedly raped at knifepoint by Dalton Ramsey, 28, after he convinced the teenager to meet him by offering to drive her to Pennsylvania to meet her boyfriend, police said.

Ramsey, who had met the victim online, allegedly detoured to B.T. Brown Reservoir in Coweta County, Georgia, on September 5 where he allegedly bound the girl's hands with tape before raping her whilst holding a knife to her throat, reports the Times Herald.

The suspect then allowed the victim, who is from Harris County, to use her phone and she quickly shared her location with her boyfriend before using the app Noonlight to alert authorities of where she was, Coweta County Sherriff's Office said.

What is the Noonlight app?

The Noonlight app allows users to send a distress call, allowing the company to track their phone and alert the authorities.

Once opened, the app asks users to hold down a circular button on their screen until they are safe.

When the user is safe, they can release the button and enter their 4-digit passcode within a certain amount of time.

But if a person is still in danger, they can release the button and not enter the passcode.

In these cases, the Noonlight team contacts the police with the person's exact location and emergency.

Her boyfriend searched for the B.T. Brown Reservoir online and found an image of a sign warning people that an alligator had been sighted in the area before sending it to the victim, reports Fox 5.

The victim confirmed that she had seen the sign outside the park, police said.

Ramsey, who was seen on CCTV pulling up outside the park in his grey sedan, then drove the girl along the highway.

But the victim quickly used the app Noonlight to send a distress call, allowing the company to track her phone and alert authorities.

Once the Noonlight app is opened, if the user does not type in a passcode within a certain amount of time, the app will try to contact them.

The girl managed to respond and type the word 'rape' and a description of Ramsey's car, meaning authorities were able to quickly track down the victim and the suspect.

Police in the nearby Habersham County pulled over Ramsey's car and rescued the teenager before arresting the suspect at around 5.20am on September 6, the morning after the victim was abducted.

The victim has since been reunited with her family.

Ramsey is currently in custody at Habersham County Sheriff's office where he is facing charges of kidnapping.

Once released from Habersham County, Ramsey will be transferred to Coweta County to face charges of rape, kidnapping, aggravated assault with a weapon and possession of a knife during the commission of a crime, police spokesman Toby Nix said.
