Police were originally calling the fire near Ohio State University that killed five students early Sunday morning “suspicious” but have now found evidence leading to a cause of arson.

In turn, the deaths of three women from Ohio University in Athens and two men from OSU are now being classified as homicides.

In the student-owned home located just off of the OSU campus, accelerant was found leading to the belief of arson. Gasoline and kerosene could have potentially been used as accelerants in the fire; however, police are refusing to provide any additional information.

The deaths of these five students are currently being attributed to smoke inhalation and carbon monoxide poisoning, however, authorities are waiting for the results of the official toxicology tests that are expected within the next two weeks.

A reward amounting to $19,000 is being offered to anyone with any information regarding the situation that could possibly lead to an arrest. Police currently have no suspects in this case. OSU contributed $5,000 of the $19,000 and established a fire victim’s fund for the other 10 students that were living in the house that caught fire and in turn, are now left homeless.

The blaze began at approximately 4 a.m. with 10 to 20 people in the house, some of which were asleep. A 21st birthday celebration had taken place that evening in the 12-student home and was winding down at the time the fatal fire began.

Memorial services are being planned at both Ohio University and OSU for the respective students.

OSU’s President Karen A. Holbrook released a statement regarding the initial situation after a news conference Sunday afternoon in which she said, “We are clearly a community in mourning.”

“Our hearts and prayers go out to the families and friends of the young people who lost their lives and to those who were injured,” Holbrook said. “We are doing everything in our power to provide support and comfort to those in need.”
