Tampa, Florida-- There's new information tonight, about the wrong-way crash that took five lives along I-275 early Sunday morning, including four USF fraternity brothers.
The last people to see the driver of the SUV that was heading the wrong way are speaking out.

Scott Enfinger and Christina Baker were the last people to see and speak with 28-year-old Daniel Morris, and while they offered insight, they had few answers.
Scott Enfinger is still clearly shaken. His hands and voice trembled as he spoke today about the moments leading up to the head-on crash.
His best friend, a man he called his brother has been labeled a monster by those who've seen the accident's aftermath.
"And for everybody to think that he's this horrible person, it rips me apart more than anyone will ever know," said Enfinger.
"He would help anybody he could," added Christina Baker.
It was Christina's voice on the 911 call telling Tampa police Morris had grabbed the keys and taken off in their white, 2001 Ford Expedition without their permission.

They'd been drinking, she admits, and told the dispatcher Daniel was upset.
But Scott says while there had been an argument between himself and his father, Daniel, helped settle it. He was fine. Or so he thought.
"As far as I could tell, there was no upset - there was no nothing. He smiled to us - he made a joke to us before he walked out," he said.
But before they knew it, Morris had swiped their SUV and taken off. Fast.
"You know he was going and made such an abrupt left turn that the back driver's side wheel had come off the ground," said Enfinger.
Morris's relatives in Michigan have speculated Daniel was drugged. They suggest someone must have slipped the 28-year-old something for him to behave so erratically.
But the Enfingers say that's not true. They admit they'd been drinking that night, but that was all.
They wish they had an explanation.
"If there were anything that could have been done, believe me, I would have done whatever it takes to stop him from doing this to himself, or anyone else. Especially anybody else," said Scott Enfinger.

The Enfingers say they just want to be left alone now. They say they have received death threats as a result of this.
Scott Enfinger repeatedly relayed their sympathies to the victims' families. The couple have five children of their own, and say they can't imagine the grief being felt by the parents of the young men killed.
