Fire marshal: Rolando McClain house fire ruled an arson

The State of Alabama Fire Marshal's Office released a statement on Friday about the the December fire that destroyed a house owned by NFL linebacker Rolando McClain in Tuscaloosa County, Ala. 

The statement says that an investigation "determined the fire to have been intentionally set" but that "no arrests have been made at this time and the investigation continues."

The marshal, Ed Paulk, said in an interview with AL.com that his office will not disclose how they believe the fire began.

"We have concluded the scene examination and we have determined it was the result of an incendiary act," Paulk said in an interview with AL.com.

Paulk said his office won't say how they believe the fire was set because only they and perpetrator or perpetrators know how it was set. "So we're going to be real tight lipped," he said.

McClain played at Alabama for three seasons before being selected in the first round of the 2010 draft. He played last season with the Dallas Cowboys and is set to enter unrestricted free agency.
