COLLEGE PARK, Md.— The shooter in a murder-suicide Tuesday just off the University of Maryland campus worked briefly for the campus police, authorities said Wednesday.

Dayvon Maurice Green, a graduate student in engineering on the College Park campus, worked as a police auxiliary officer for about two weeks in August and September, said university police spokesman Marc Limansky. Green did not carry a badge or a gun, but had a police radio that would allow him to summon a sworn officer if he spotted trouble.

Green was fired after he twice failed to show up for work, Limansky said.

Police say Green shot two roommates — one fatally — and then killed himself early Tuesday after setting a series of small fires in and around the home he and the roommates rented.

Green’s family told police that he had been suffering from mental illness for at least a year and had been prescribed medication.

University officials have said they were not aware of Green’s mental health problems.

Green used a 9mm handgun that he purchased legally last year in the shootings. Police also found a bag of weapons, including a baseball bat, a machete and a semi-automatic rifle, purchased legally by Green on Jan. 18.

Killed in the shooting was Stephen Alex Rane, 22, of Silver Spring, a senior who was working toward a double major in English and linguistics.

Meanwhile, the stepfather of the student who was wounded said his stepson is recovering from the shooting and will return to school.

Christian Merz said Wednesday that Neal Oa, 22, was shot in the leg while running from Green. Police said Wednesday that Oa has been released from the hospital.

Merz says his stepson had known his housemates only since last summer. He says Oa considered Green to be “pretty smart” but “a little different.”

Merz says his stepson was lucky and that his family has suffered but that the families of Green and Rane are suffering more.
