Rion Christopher Morgan, 31, was one of eight people killed on September 10, 2017, when a gunman opened fire at a Dallas Cowboys watch party at a home on West Spring Creek Parkway in Plano. The attacker, identified as 32-year-old Spencer James Hight, entered the residence around 8 p.m., shot multiple people and was then fatally shot by responding police officers. A ninth person was wounded and survived.

Morgan, an African American man from Plano, graduated from the University of Texas at Dallas in 2008 with a degree in Business Administration and later worked as a manager in UTD’s Office of Information Technology. Colleagues and friends remembered him as charismatic, generous, and a mentor on campus. He had been a groomsman in Spencer and Meredith Hight’s 2011 wedding; several victims were close to the couple.

If anyone knew Rion or was at that gathering and has information to share, please come forward.
