A woman who answered the phone at Ms. Love’s family home in Maryland said, “No comment.” Mr. Huguely’s family did not return a call seeking comment.

The top-ranked Virginia’s men’s lacrosse team is expected to be the top seed heading into this month’s N.C.A.A. tournament. The women’s team is in the top five and considered to be a strong contender to advance to the national semifinals.

University of Virginia lacrosse has endured its share of recent tragedy: the former men’s captain Will Barrow died of an apparent suicide in 2008 and the longtime assistant media relations director Michael Colley, who was the main contact for the men’s lacrosse team, died of a heart attack in July. Now the program is in shock again.

“Charlottesville is just a wonderful place,” Mr. Longo said. “Kids from all over the country come here, the best and brightest, and these are two of them, two successful athletes.

“It’s just an unbelievable situation. These are not the kinds of things we see in this community.”

In a news conference Monday, Virginia’s athletic director, Craig Littlepage, said Love was described by her teammates as “an angel.” He said that no decision had been made on the future of each team. Tuesday is the final day of classes at Virginia, with a reading day Wednesday and final exams beginning Thursday.

Dom Starsia, the Virginia men’s lacrosse coach, met with his team on Monday afternoon and delivered the general message of not being afraid to seek help.
