Tampa, FL -- We're learning more about the person believed to have been driving the 2001 Ford Expedition that killed four USF fraternity brothers.
As friends and family mourn the four fraternity brothers killed in a fiery head-on crash, investigators were still working to positively identify the fifth victim.

He's a man in his 20's, they say, but his identification has been complicated by the condition of the driver's body. Burned beyond recognition.
"We're working with people who think they know who it is," said FHP Sgt. Steve Gaskins.
Confirmation will take the use of medical records, or if necessary DNA -- a process that could take hours, but perhaps days.
With a positive identification the Florida Highway Patrol says it will help them retrace the driver's footsteps to where he likely entered the highway.
"Reports that we have," said Gaskins, "is that he was at least in the Bearss Avenue area coming southbound in the northbound lanes."
As investigators work to confirm the driver's identity, 10 News has learned from two sources that the man likely behind the wheel had taken the SUV from a late night party.
They say the driver's significant other contacted police and told them the driver was emotionally distressed and possibly on a mission to take his own life.
It's an assertion supported, perhaps, by the video leading up to the crash. Investigators say the SUV drove in a straight line in the center lane of on-coming traffic at high speed, and never appeared to attempt to avoid the other drivers.
"Based upon that video which we've all seen, I don't see a lot of deviation in his path on his part," said Gaskins.
FHP investigators say they have medical information that would be unique to the person they believe was driving the SUV. If the medical examiner says it's a match, they say they'll be able to identify the driver very shortly after that.
The fraternity chapter's president, Jigar Patel, reacting to the newest revelation, said,"the motivation is of little consequence to the tragic outcome."
"It's out of our hands," he said.
At this point, Patel said they can only concentrate on what they can do.
