 BLACKSBURG, Va. (AP) — Two Virginia Tech engineering students have been arrested in connection with the death of a 13-year-old girl whose disappearance last week from her Virginia home set off a frantic, four-day search. 
 
 Blacksburg Police say David Eisenhauer, 18, was arrested Saturday and charged with first-degree murder and abduction in the death of Nicole Madison Lovell, who disappeared from her home Wednesday. Natalie Keepers, of Laurel, Maryland, was arrested Sunday and faces charges of improper disposal of a body and accessory after the fact in the commission of a felony. 
 
 Both are being held without bond at the Montgomery County Jail. 
 
 "Based on the evidence collected to date, investigators have determined that Eisenhauer and Nicole were acquainted prior to her disappearance. Eisenhauer used this relationship to his advantage to abduct the 13-year-old and then kill her. Keepers helped Eisenhauer dispose of Nicole's body," Blacksburg police said in a statement. 
 
 Virginia State Police located Lovell's remains Saturday afternoon in Surry County, North Carolina, just over the Virginia border. Hours later, police announced the arrest of Eisenhauer, a freshman from Columbia, Maryland. 
 
 State police spokeswoman Corrine Geller said Sunday that a search and recovery team is combing a pond on the Virginia Tech Campus. She would not say what officials are trying to find. 
 
 The Roanoke Times newspaper quoted to Blacksburg Police Chief Anthony Wilson as saying that Eisenhauer has not confessed to involvement in Lovell's death and did not give police information that led to the discovery of her body. 
 
 Police initially charged Eisenhauer with abduction; he was charged with murder once the girl's remains were found. 
 
 The girl had been missing since last week. Her family says she disappeared after pushing a dresser in front of her bedroom door and climbing out a window. Lovell's family members did not immediately return messages seeking comment Sunday. 
 
 Eisenhauer was as a standout track and field athlete in high school, who was named Boys Indoor Track Performer of the Year by the Baltimore Sun in March. The Sun said Eisenhauer had moved to Columbia from Yakima, Washington for his junior year and quickly became a star on the East Coast. His coach told the newspaper that Eisenhauer was "the best-kept secret in Maryland." 
 
 Joe Keating, who said he was a co-captain alongside Eisenhauer on the Wilde Lake High School track team, described him as a normal kid who seemed to enjoy being at school and never started any problems. Keating said he's "appalled" by the thought that Eisenhauer could be involved in Lovell's death. 
 
 "All of my friends that knew him, that graduated with him, as well as everyone on the team, we're just in total shock about this entire thing. We would never have seen this coming," Keating said. 
 
 Virginia Tech said on its website that Eisenhauer was a freshman engineering major at the school and that hundreds of students and researchers had assisted in the search for Lovell. The school said in a statement Saturday that he has been suspended from the university. 
 
 A number listed for Eisenhauer's parents was busy on Sunday. An official at the county jail where he is being held would not say whether he has a lawyer. 
 
 Virginia Tech president Tim Sands said the case left the school community "in a state of shock and sadness." 
 
 "Speaking on behalf of our community, let me say that our hearts go out to Nicole's family and friends," he said in a statement posted to the school's website.

 Eisenhauer, of Columbia, Maryland, is a freshman engineering major at Virginia Tech and was staying at a dorm on campus where he was arrested, police and the university said. He is being held without bail at Montgomery County Jail. 
 
 The FBI and state and local police were among the agencies searching for Lovell. 
 
 Virginia Tech President Tim Sands said the girl's death and the arrest "has everyone in a state of shock and sadness." 
 
 "Speaking on behalf of our community, let me say that our hearts go out to Nicole's family and friends," Virginia Tech President Tim Sands said.
– A 13-year-old girl who went missing from her home in Blacksburg, Va., early Wednesday was found dead on a North Carolina roadside late Saturday, and authorities quickly added a first-degree murder charge for the 18-year-old Virginia Tech freshman already charged in her abduction, reports NBC News. Police also arrested Maryland resident Natalie Keepers for allegedly helping to dispose of the body, reports the AP. Nichole Lovell had shoved a dresser in front of her bedroom door and left through a window; the search for the child was urgent from the start because Nichole was recipient of a liver transplant and had gone missing without her medication. David Eisenhauer, an engineering student and high school track standout from Columbia, Md., was charged early Saturday in Nichole's disappearance, reports the Baltimore Sun. "This is a sad day for the Blacksburg community. As a parent, I know that this is an unbearable loss for the Lovell family," Blacksburg's mayor says. The city's police chief notes that Eisenhauer didn't tell them where Nichole's body was, and that investigators are still trying to piece together how the two met. Because Eisenhauer is charged with a felony, Virginia Tech has placed him on immediate interim suspension, the university notes in a press release. Nichole's body was being returned to Blacksburg overnight for an autopsy.
