Skorik told media the gunman was recently transported from Bay Area Medical Center in Marinette, to St. Vincent's Hospital in Green Bay, and is considered to be in "grave condition," reports CBS affiliate WFRV.

As part of the ongoing investigation, authorities have interviewed the alleged gunman's parents, as well as classmates; they say this act was "uncharacteristic" of his personality.

The student armed with a handgun held nearly two dozen students and a teacher hostage in Marinette High School for about five hours before shooting himself when police broke into the classroom, authorities said. No other injuries were reported.

Authorities also found more bullets in a duffel bag matching the guns recovered at the scene.

Police are still withholding the 911 tape citing it as part of the criminal investigation.
