Three people were shot and two were killed - all of them students - early Tuesday morning in an apparent murder-suicide near the University of Maryland campus in College Park.
The shooter has been identified as Dayvon Green, 23, of College Park. He was an engineering graduate student at the university who previously attended Morgan State University. He was a NASA student ambassador.
It was confirmed Wednesday that Green was schizophrenic and had a bipolar disorder.
The deceased victim is identified as Stephen Alex Rane, 22. He was an undergraduate.
A vigil was held Tuesday night for the victims. Many of those in attendance were friends of Rane.
Students say Rane was as kind as they come.
UMd. senior Evan Morsell said, "Always asking if you need help with anything, so I'd say Stephen was a pretty great guy."
"Every time I want to stress out about something silly, I'll just think of him, because he just knew what was important. He always smiled no matter what," added senior Emily Makhlouf.
Prince George's County Police officials say the shooting happened at a home in the 8700 block of 36th Avenue just before 1 a.m. Authorities say that Green, who lived inside the home, started a fire in the basement, forcing all of the occupants outside.
Once outside the house, Green opened fire, shooting both of his roommates several times, sources say, before going back inside and taking his own life. One of the roommates died from his injuries at the hospital, while the other, an undergraduate, was hospitalized with non-life threatening injures.
Police recovered a handgun next to Green's body as well as a fully loaded semi-automatic weapon and machete.
Maryland graduate student Jithin George heard the gunshots. The last shot he heard was the armed engineering graduate student taking his own life in the back yard.
""I heard a couple of shots (in) quick succession," George says.
Firefighters were able to quickly extinguish the blaze. The identities of the two victims are being withheld while county police officials make contact with their families.
On campus Tuesday, in the halls of the School of Engineering, the murder-suicide was particularly felt.
Both the shooter and the victim who was killed were engineering students. Rane, originally from West Lafayette, Indiana.
In an email sent to the campus community Tuesday afternoon, University of Maryland President Wallace Loh called the shooting a "tragic day for our beloved university community."
"As we mourn this incredible loss, community and support are essential to the healing process," Loh said in the email. He added that support services are being made available to members of the campus community who wished to seek it out.
