On Tuesday afternoon, Prince George's County police identified the alleged shooter from an early morning murder-suicide in College Park as 23-year-old Dayvon Maurice Green.
According to police, Green was an engineering graduate student at the University of Maryland. Speaking to reporters outside the scene of the shooting, UMD President Wallace Loh said he believed Green had been at the university for about a year.
Green earned his undergraduate degree from Morgan State University in Baltimore, officials said. The Baltimore Sun reports that he was a member of Phi Beta Sigma's Gamma chapter and maintained a grade point average above 3.5.
Green also participated in the NASA Student Ambassador program and worked at the NASA Goddard Space Flight Center in Greenbelt.
In a profile from his internship, Green described his area of research interest as "quality control and reliability studies including the reliability of robotic satellite servicing missions for commercial and military communications spacecraft."
Two professors who worked with Green told Capital News Service that the shooting came a shock given what they knew of him.
“I have never seen any streaks of unusual behavior from him. He worked with a team and everyone was happy with his work,” said Madhumi Mitra, an associate professor in the Department of Natural Science at University of Maryland Eastern Shore.
Julie Parker, a spokeswoman for the PGPD, said that Green's family told investigators he had been suffering from a mental illness for at least a year at the time of the shooting. He had been prescribed medication for that illness, she added.
According to UMD officials, Green was not treated at the university during his time as a student.
Green was found dead Tuesday in the backyard of the home at 8706 36th Ave. in College Park, where he reportedly turned a 9mm handgun on himself after shooting two of his roommates.
One—22-year-old UMD undergraduate Stephen Alex Rane—was pronounced dead at a hospital. The other, also a 22-year-old undergraduate, suffered non-life-threatening injuries.
Police said they also located additional weapons in Green's possession, including a baseball bat, a machete, and a .22-caliber semiautomatic pistol.
