No Abnormalities Found in Cho's Brain

In a condition update of one of the shooting victims, the parents of Justin Klein, 20, of Catonsville, Md., said in a statement: "His medical condition continues to improve, and he is expected to be released from the hospital shortly." Their statement did not say where he is hospitalized.

A junior majoring in engineering science and mechanics, Klein suffered three gunshot wounds, two to his right leg and one to his left elbow, according to the family's statement.

Klein is a dean's list student and an officer of the Tau Beta Pi engineering honor society. A lifelong resident of Catonsville, he is a 2004 graduate of Catonsville High School, where he belonged to the honor and math societies. He is an Eagle Scout and a member of Catonsville United Methodist Church.

His parents, Ross and Diane Klein, and brother, Ryan, released a joint statement saying, "Justin's courage and strength have been an inspiration to his family, friends and fellow Hokies. Justin and his family have been overwhelmed with expressions of concern, love and support."

And in Alexandria yesterday, 32 mothers whose children attend the same preschool dressed in black and lay side by side in front of City Hall to honor the victims of the shootings. Each woman draped a thick ribbon of orange and maroon -- Virginia Tech's colors -- around her neck.

Several of the women said they were so troubled by the shootings that they felt they had to do something, anything to raise awareness about Virginia's gun control laws.

"It takes longer for me to get my car washed than it takes to get a gun" in Virginia, said Abigail Spangler, an Alexandria mother of three who organized the event. "There's just something wrong about that."
