-- The mother of a stabbing victim was able to meet the hero who helped save her son's life on Sunday.
Margie Fletcher's 21-year-old son, Micah Fletcher, is still in the hospital after being injured in a stabbing on a Portland, Oregon, train on May 26 that left two other men dead.
"He was terrified," Knipe told ABC affiliate KATU. "He was scared. There was blood coming through his fingers or seeping through his fingers ... He was sitting there screaming out. 'Somebody help me. Help me. I've been stabbed.'"
Knipe said he put pressure on Micah Fletcher's wounds, tried to keep him calm and called his mother. When Knipe reached her, he told her that he was helping her son and that he was going to be taken to a hospital.
"All I know is I was in the right place at the right time and knew what needed to be done just to get him to stay alive," Knipe told KATU.
Margie Fletcher said she was grateful for the opportunity to meet Knipe and thank him in person.
"I can't thank him enough. Never, ever. There's nothing I can do that will ever make up for what he did," she told KATU.
According to police, Jeremy Christian, 35, allegedly yelled hateful comments at two teen girls while riding the light rail. One of the girls was wearing a hijab. Ricky John Best, 53; Taliesin Myrddin Namkai Meche, 23; and Micah Fletcher went to the girls' aid, and Christian attacked the men. Best and Meche died in the stabbing.
Christian is facing two counts of aggravated murder, attempted murder, two counts of intimidation and possession of a restricted weapon by a felon.
Christian is scheduled to be arraigned on Tuesday.
