A suspected carbon monoxide leak at Evergreen State College in Olympia, Washington, Monday evening left one student dead, with two other students and a police officer injured.

A student residence manager called campus police after being unable to contact the students. The campus police broke down the door of the building at around 8:30 p.m. local time.

The Thurston County Coroner’s Office identified the deceased student as Jonathan Rodriguez, 21, according to KOMO-TV.

The two students and the responding officer who performed emergency CPR were all taken to area hospitals.

The unnamed officer was released Tuesday, but no update has been given regarding the two students. They had shown symptoms “consistent with carbon monoxide poisoning,” school officials said in a release.

School officials also noted that a contractor working in the Modular Apartments housing area on campus had responded to carbon monoxide alarms earlier Monday. Students living near the affected building said they heard alarms before campus police showed up.

“The alarms were going off for a couple of minutes. The police showed up, then the fire department showed up,” senior Kris Pennington, who lives next door, told KOMO-TV, adding that the alarms go off a lot.

“From what I’m aware of, the only source of carbon monoxide would be the water heaters,” Mr. Pennington added.

“This is a tragedy, and we grieve for our students and families. The safety of students, staff and faculty remain Evergreen’s top priority,” Evergreen President John Carmichael said in a statement.

The incident is being investigated by the Washington State Patrol, school officials said.
