The PGPD released the following description of the incident Tuesday afternoon:

The Prince George's County Police Department is investigating a murder-suicide in College Park. On February 12, 2013, shortly before 1:00 am, police officers were called to the 8700 block of 36th Avenue for the report of a shooting. Once on scene, police officers discovered three people had been shot. The investigation reveals the suspect set multiple small fires in and around the backyard of his home. One of his roommates woke up to the flames. He alerted a second roommate. They find the suspect in the back of the home and the three agree to put out the flames. While walking back inside to get water, one of the roommates notices the suspect reaching into his waistband and pulling out a gun. That roommate begins to run. He hears gunshots, realizes he's been hit and runs to a neighbor for help. The other roommate collapses outside of the home after being shot multiple times. The suspect then walks into the backyard and turns the gun on himself. Police officers recovered a handgun next to the suspect's body as well as a bag of weapons to include a baseball bat, a machete and a fully-loaded semi-automatic weapon and ammunition. The shooter 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. The victim who collapsed outside was pronounced dead at a local hospital. He 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 non-life threatening injuries. Homicide detectives are working closely with the ATF to determine when and how the guns were purchased.

UMD President Wallace Loh, who spoke to reporters outside of the home where the shooting occurred, called it a "great tragedy for the University of Maryland."

He noted that the university had increased its complement of mental health professionals in recent years but declined to speculate about the specifics of Green's case.

Update, 1:14 p.m.: "Our peaceful community is shaken when such a violent act is committed so close to home," reads a statement from the University of Maryland Student Government Association.

The SGA says a memorial gathering to 'begin the healing process' has been scheduled for 7 p.m. in the Memorial Chapel.

Update, 12:35 p.m.: Prince George's County police say they will release more information on Tuesday's murder-suicide at a 2 p.m. press conference near the scene of the shooting.

Patch will have a full roundup shortly after the conference ends.

Update, 11:16 a.m.: Authorities say two University of Maryland students are dead and another injured after a murder-suicide Tuesday morning in College Park.

According to Prince George's County Police Department spokesperson Julie Parker, officers responded to the 8700 block of 36th Ave. just before 1 a.m. When they arrived, they found three men suffering from gunshot wounds and a small fire showing from the side of a house.

Police believe the suspect started several small fires in the basement and backyard of the home, which he shared with two other men.

When his roommates came outside to discuss the fires with the suspect, he shot one of them, according to police.

The second roommate attempted to flee the scene but was also shot, officials said. The suspect then went around to the back of the home and took his own life.

One victim was pronounced dead at an area hospital, while the second victim sustained injuries that were not life-threatening. The suspect was pronounced dead at the scene.

The identities of the victims and the suspect have not yet been released, as authorities are still notifying family members of the deceased.

Police say they recovered a weapon at the scene and are not looking for any additional suspects. An earlier report that police were searching for possible shooters in a tan Honda Odyssey turned out to be the result of a miscommunication.

In a statement, University of Maryland President Wallace Loh said he was "shocked and saddened by this morning's tragic events."

"I ask that the entire University of Maryland family come together during this time of grief," he added. "On campus, our places of worship and the Counseling Center are open for those who need support and comfort."
