The family of the gunman who shot dead 32 people has apologized for the "excruciating grief" inflicted on a US campus, saying as the nation mourned that he had made "the world weep."
"Each of these people had so much love, talent and gifts to offer, and their lives were cut short by a horrible and senseless act," a statement issued on Friday by the family of Cho Seung-hui said.
"We are humbled by this darkness. We feel hopeless, helpless and lost," they said in the statement, which named all 32 of the victims who died in the shooting at Virginia Tech university on Monday.
Issued by 23-year-old Cho's sister, Cho Sun-kyung, the statement said that her brother was "quiet and reserved," and had "struggled to fit in."
"We never could have envisioned that he was capable of so much violence," the family said.
"No words can express our sadness that 32 innocent people lost their lives this week in such a terrible, senseless tragedy," the statement continued.
The statement came just after bells tolled around the country for the 27 students and five teachers mown down in a hail of gunfire when Cho rampaged through a dormitory block and a classroom complex.
Burning questions remain over whether Cho, who had been briefly hospitalized for mental health problems, should have been able to buy two guns and ammunition.
Police were probing the possibility that Cho may have confided his plans to someone else to unleash a massacre at Virginia Tech, ABC News reported.
According to the report, authorities were now seeking Cho's cellphone records from Verizon Wireless in New Jersey.
"We can never fully understand what would cause a student to take the lives of 32 innocent people," US President George W. Bush said, announcing that he had ordered a review of the questions raised by the shooting.
Top officials from the departments of education, justice and health are to travel around the country for discussions before reporting to Bush with recommendations on how to avoid such tragedies in the future.
Virginia Tech led the country in mourning on Friday, as about 1,000 people crowded onto the campus' drill-field and bowed their heads for several minutes of silence.
Amid the crying and hugging, a handful of students released 32 orange and maroon balloons each bearing a name of the dead.
"You think you've cried it all out, and then there's more," said Christine Backhus, a psychology senior from Centreville, Virginia, the same town Cho called home, who helped organize the balloon release.
Late on Friday, a huge crowd of maroon-and-orange-shirted fans turned up at a baseball game, confirming the community was ready to move ahead.
Virginia Tech athletic director Jim Weaver said the university wanted to create "an opportunity for all the students and members of the community to get off that event of Monday."
Masses, prayers and memorial services were held around the country by the university's alumni, with a special prayer service for the victims to be held yesterday in the National Cathedral in Washington.
The Virginia Tech memorial day fell on the eighth anniversary of the massacre at Columbine High School in Colorado.
