David Eisenhauer, 18, and Natalie Keepers, 19, had a bright future ahead of them but are now both behind bars and charged in connection with the murder of the teen.

Last year, Eisenhauer was featured as "Athlete of the Week" on a TV station in his home town of Columbia, Maryland. 

Keepers once interned with NASA and appeared in a video slamming the high cost of universities. 

It has emerged that 13-year-old Lovell met Eisenhauer on a dating website for teens.

Last Tuesday night she ran away from her home near the college campus. Her distraught dad put out a desperate plea on social media: "Nicole, honey, if you see this if you're out there you can come to me. I'm not mad at you. I'm worried about you. Your family is worried about you. Just come home."

There was a massive search - made more urgent by the fact that she was a liver transplant recipient who required daily medication.

Virginia Tech engineering students used drones to look for the missing teen. Little did the volunteer drone operators know that two students from their own engineering department were allegedly involved in her murder.

Rose Mooney directed the aerial search of the drones. She told INSIDE EDITION: "It is a little bit more surprising and shocking. It is unfortunate, no matter who it is. We certainly feel really bad for the family." 

Eisenhauer was allegedly traced through Lovell’s computer and placed under arrest. Hours later, the teen's body was found 80 miles away in North Carolina.

Natalie Keepers was charged with helping him dispose of Lovell’s body.

The murdered child's father posted his heartbreak on Facebook: “Devastated to learn that my daughter has been found dead. I'm so in shock I know nothing more to say. I'm broken!”

The suspects appeared in Montgomery County court on Monday. Neither entered a plea.
