Prince George's County Police Police have identified the suspected shooter in an apparent murder-suicide as Dayvon Maurice Green, a graduate student at the University of Maryland.
Authorities say Green opened fire on his two housemates in an off-campus residence in College Park, killing one and wounding the other before turning the gun on himself.
Police said Green had been suffering from an unspecified mental illness before the shooting. He had purchased the gun legally about one year ago.
Green was studying computer science. He had completed an undergraduate degree at Morgan State University.
Police said that shortly after 1 a.m. Tuesday, he set a fire in the basement of his rented house in the 8700 block of 36th Avenue near University Boulevard. As his two housemates ran outside and confronted him, he opened fire, according to authorities.
Green then went to the rear of the house and killed himself, police said.
One housemate, who sustained non-life-threatening injuries, ran to a neighbor's house for help. The other victim later died at a local hospital.
"All I heard was about six to seven shots going, 'pop pop pop,' and then about 15 minutes later, we saw the cops," neighbor Jithin George told News4's Megan McGrath.
The identities of the victims -- both male University of Maryland students -- have not yet been released. It is unknown whether they were graduate or undergraduate students.
The university sent an alert to students around 1:15 a.m., warning them that a shooting had been reported off-campus.
