COLLEGE PARK, Md. - Police in Prince George's County say a University of Maryland student shot two housemates, one fatally, in an off-campus residence and then killed himself.
The shooting happened at around 1 a.m. Tuesday in the 8700 block of 36th Avenue in College Park.
The shooter, officials say is a NASA scholar studying computer science. He is identified as 23-year-old Dayvon Maurice Green of 36th Avenue in College Park. Green was a graduate student at the University of Maryland. Police say he had documented mental health concerns.
Green is believed to have set a fire in the backyard of the home early Tuesday. Police say he pulled a gun from his waistband and shot his housemates when they confronted him. Police recovered a handgun and a bag of weapons next to Green's body. Inside that bag, they say, were a baseball bat, a machete, a fully-loaded semi-automatic weapon and ammunition.
The deceased victim is identified as 22-year-old Stephen Alex Rane of Silver Spring. He was an undergraduate at the university. The surviving victim is also a 22-year-old undergraduate. He has injuries not believed to be life-threatening.
Homicide detectives are working closely with the ATF to determine when and how the guns were purchased but preliminarily, PG County Police say the 9mm hand gun used was legally purchased in Baltimore County.
UMD senior PauI Rowe is a neighbor of the three students involved in the incident. He said he heard about 10 shots fired at about 1 a.m.
"We couldn't decide if it was firecrackers or gunshots," Rowe said. "Figured if it was firecrackers, we'll find out later. If it's gunshots, we should really stay inside."
Rowe said he and friends stayed inside for a few minutes until everything got quiet. When they went outside, he said law enforcement vehicles were everywhere on the street.
"(Cars were) lined up in our yard and in our road," Rowe said. "They responded pretty quickly."
Rowe said he doesn't know the three students involved in the incident but wanted to get to know them because they seemed cool.
A student that lives in a home next door to where the incident happened says he hit the lights in his room and ducked behind a chair when he heard gunshots. That same student said when he peeked out of his home, he saw a body on the front steps of his neighbors.
