The final student hospitalized in last month's stabbing spree at a Pennsylvania high school is back home.

Franklin Regional High School sophomore Greg Keener was released from a hospital Saturday. The 15-year-old was one of 20 students wounded when authorities say a classmate wielding two kitchen knives rampaged through the suburban Pittsburgh school. A security guard was also wounded in the April 9 attacks.

Keener had been moved out of the intensive care unit earlier in the week. His family says he has been able to engage in daily activities including watching the NHL playoffs.

Sixteen-year-old Alex Hribal has been charged as an adult with 21 counts of attempted homicide and aggravated assault. He is scheduled for a June 4 preliminary hearing.
