The investigation showed that Nicole Madison Lovell, the 13-year old Virginia girl, was stabbed to death the very day she disappeared, according to authorities.

Mary Pettitt, The Commonwealth's Attorney, announced in a brief news conference Tuesday, Feb. 2, that Lovell died on Wednesday, Jan. 27. The result is contrary to the initial investigation that the teen died Saturday, Jan. 30.

ABC News reported that the preliminary hearings are already set late March and neither of the two suspects, David Eisenhauer, 18, and Natalie Keepers, 19, has entered a plea.

David Eisenhauer, 18, was arrested inside his campus residence first charged with abduction. Later on, after Lovell's remains were found in Surry County, North Carolina, he was charged with murder. Eisenhauer was a freshman engineering student from Columbia, Maryland.

Arrested Sunday, Jan. 31, the second suspect, Natalie M. Keepers, first charged with improper disposal of body and accessory after the fact will have her charge changed to accessory before the fact. Keepers was a sophomore engineering student of Lauren.

Pettitt still has yet to comment about the reason why the change has been made or give any information about the crime.

During the conference, Tammy Weeks, Nicole's mother, has broken down in tears as she shared stories of how her daughter grappled with serious illness ever since she was born and how Nicole and their family has struggled so much just for her to survive.

According to Weeks, when Nicole arrived in their family, they have noticed that her abdomen had become swollen. They found out it was liver cancer. At an early age, 10-month old Nicole underwent a liver transplant and has been under a twice daily medication ever since.

At the age of four, Nicole has been diagnosed with Non-hodgkin's lymphoma, then acute respiratory syndrome, which led her into coma for nearly 6 months. While bedridden, he developed MRSA.

"She had a 1 percent chance of survival," Tammy Weeks said. "Once again, she beat the odds," she added.

She also told The Washington Post how Nicole has always been bullied by other kids at school, saying: "She was telling me that girls were saying she was fat and talking about her scars from her transplant."

Nicole's family is still in shock of what happened to her. David Lovell, his father, is even demanding answers.

"These two individuals took my daughter from this planet and I want to know why," he said in an interview. "I want all the information I can get," he added.
