Killer May Have Showed Appetite for Violence as Child

April 21, 2007 — -- Though it's unclear if he told anyone about his plans to stage a shooting rampage at Virginia Tech, from childhood, Seung-Hui Cho showed an appetite for brutality, according to a new report.

The Washington Post reports that while Cho was unusually quiet as a child -- according to relatives, he refused to respond to greetings and didn't want to be hugged -- when he fought with his older sister, Sun-Kyung Cho, his actions spoke volumes. Relatives say he punched her with shocking force.

Despite signs of trouble, Cho's mother didn't seek treatment for him because he did well in school, the Washington Post reports.

But in their first public statement since the massacre, on Friday, Cho's family said that their son "has made the world weep" and that they are now "living a nightmare."

The statement, released to the Associated Press by Sun-Kyung Cho, says the family feels "hopeless, helpless and lost," after the 23-year old Va. Tech senior took the lives of 32 people.

"We are humbled by this darkness," wrote 25-year old Sun Kyung Cho. "This is someone that I grew up with and loved. Now I feel like I didn't know this person ... My brother was quiet and reserved, yet struggled to fit in. We never could have envisioned that he was capable of so much violence."

But there are signs that Cho's family, or others, could have known he was plotting a massacre.

On Friday, ABC News obtained court documents that show police are probing the possibility that Seung-Hui Cho may have confided his plans to someone else. In a search warrant affidavit filed by Virginia State Police Friday, authorities say the shooter "may have communicated with others concerning his plans to carry out attacks on students and faculty at Virginia Tech."

The affidavit also revealed that Cho kept up contact with his parents, saying, "an interview with Seung-Hui Cho's family revealed her often used a cellular telephone to communicate. He normally spoke to his parents on Sunday evenings."
