Tech Mogul's Alleged Murder Victim Hailed for Heroism

Corey Mattison is credited with a final act of heroism to protect his family.

— -- A prominent social media entrepreneur was arraigned for first-degree murder Tuesday, accused of gunning down his ex-wife’s new husband, while the victim is being credited with a final act of heroism to protect his family.

Tech mogul Minh Nguyen is accused of killing Corey Mattison. Mattison, a former minor league pitcher with the St. Louis Cardinals organization, was married to Denise Mattison for nearly six months before he was fatally shot.

“He was my knight in shining armor,” Denise Mattison said.

Authorities are still investigating the causes of the shooting, they said.

Denise Mattison said her thoughts lie with her husband and his final act.

“He literally laid his life down to save me, and there’s not a question of that,” she said.
