Virginia Tech distance runner David Eisenhauer was arrested Saturday and charged with murdering 13-year-old Nicole Lovell.

Eisenhauer, 18, was removed from Virginia Tech’s athletic website and the school released a statement saying that he was placed on immediate interim suspension due to a felony arrest, per school policy. He was majoring in engineering and is a former high school state champion in track.

Blacksburg Police Chief Anthony Wilson announced Saturday night that Lovell’s remains had been found and that Eisenhauer was in custody.

“This was a huge investigation that involved, unfortunately, taking apart the life of a 13-year-old and figuring out where she was and who she had come in contact with,” Wilson said, via Bleacher Report. “I’m not going to go into all the specific pieces of it, but when the pieces did come together, Mr. Eisenhauer was identified.”

Police arrested a second Virginia Tech student Sunday. Natalie Keepers, a 19-year-old sophomore engineering student, was arrested after police determined she aided Eisenhauer in disposing of the body.

Lovell was a liver transplant patient who “was acquainted” with Eisenhauer before she disappeared Wednesday, according to Blacksburg, Va. police, via Deadspin.

“Eisenhauer used this relationship to his advantage, to abduct and then kill her,” Chief Wilson said.

Police have not publicly said how the two met.

Eisenhauer is being held without bond and is charged with both abduction and first-degree murder.
