Retired FBI special agent Rob Chadwick joins Brian Kilmeade to discuss the school shooting at Silver Rail Elementary in Bend, Oregon, where three children and one teacher were killed.

The man who police in Bend, Oregon, said "neutralized" the shooter who killed three children and a teacher Thursday at Silver Rail Elementary School has been identified as 36-year-old Kaylub Giamanco, a law enforcement source confirmed to Fox News Digital.

During a news conference Friday, police identified the teacher who was killed in the shooting as 25-year-old Meghan Lambert, and also announced that among the youngest of the victims was 5-year-old Rhoam Summer.

"Meghan was compassionate and had a huge heart. She always fought for the underdog and those with special needs. She was an incredible sister, daughter, niece and granddaughter. Her friends became her family," Lambert's family said in a statement read at the news conference.

Earlier Friday, Kenda Freeman said in a statement that her son, Giamanco, intervened in the attack and shot the gunman who killed three students and a teacher, The Associated Press reported.

Giamanco, a local carpenter and dad, has two daughters who attend Silver Rail, his brother Kyle Gianmaco told NBC News.

"We want the bystander who intervened to know we know he is going through a rough time, but we are grateful and we think he is a hero," Lambert's family added in the statement. "You selflessly put yourself at risk for others. We would like the other families to know they are in our thoughts and prayers. Megan loved those children and so we will show you love for her."
