MADISON, Wis. -- Madison fire investigators have cleared the scene of a fire at a fraternity house on Langdon Street, but there is still no word on what caused the fire at the Sigma Phi Epsilon fraternity house late Monday night.

The Madison Fire Department said the fire caused about $750,000 in damage.

Authorities said that the first fire call came in at about 11:40 p.m. A Madison police officer in the area said she noticed a glow coming from inside the fraternity house and went to investigate. Upon discovering the fire, Officer Angie Dyhr said she pounded on the fraternity's front door to get the attention of residents. She helped safely evacuate everyone inside.

"I have my own children. I'm thankful that I happened to be there," Dyhr said.

Dyhr has been with the police department for three years and said she recently had a joint-training session with the Madison Fire Department.

Officials said that about 25 residents are displaced.

The house's occupants lost their belongings in the midst of final exams at UW-Madison. Fraternity alumni board member Ryan Sugden said that a semester's worth of notes and books were among the students' belongings lost in the fire. He said that over half have finals on Tuesday.

Sophomore David Sachs said he lost much of the notes and books he needed for a final exam on Wednesday.

"In that situation, you don't know what to do, what to grab," Sachs said. "I left without a shirt on my back. I had to borrow a friend's."

Sachs said he has been trying work out a plan for his finals.

"It's been very stressful lately in terms of finding out about how to study, or even go about studying for finals, because I don't have my notebooks, my textbooks," Sachs said. "So, I've been getting in touch with my professors and some deans and figuring out possibilities for that."

Most of the 25 displaced Sigma Phi Epsilon members are in a similar situation. They said they're not only looking for help getting necessities, but also time and understanding.

"At this point, the faculty has been very supportive in accommodating, offering incompletes, alternative test dates, the whole 9 yards," said Dean of Students Lori Berquam.

The University Bookstore has offered free book loans to students affected by the fire and the Red Gym has made space available to study.

"The bottom line is it's really hard to recreate your notes that you've amassed over a semester of attending class, lecture, and lab. So, no doubt this is a challenge for our students," Berquam said.

But for the students in Sigma Phi Epsilon, it might be the shock that's harder to get over.

"I came here and I walked up to it and I was getting water in my face from the hoses and smelling the smoke, and I was like, 'Aw man, it's all over,'" said Eddie Anderson, a junior.

"It wasn't exactly how I planned to end this year, but you roll with the punches," Sachs said.

The fraternity chapter's alumni board and national organization are helping to make temporary and summer housing arrangements for students. There were about a dozen who'd planned to live there next summer, and 20 next year. The dean of students is also offering temporary housing in the short course dorms for $20 a night, an option the university developed after dealing with two other campus fires this year.

According to the fraternity's Web site, this house had $500,000 in damage from an early morning fire on June 17, 1999.
