The man who last saw Daniel Morris before he sped down the highway and killed four people says Morris was not intoxicated or on drugs.
Scott Enfinger has been the focus of intense scrutiny.
"I need everybody to know it's not anything that we could have prevented," said Enfinger.
Saturday night was Enfinger's girlfriend's birthday.
To celebrate, they had a barbecue.
"My children were sleeping, nobody was out of hand, everything was awesome," Enfinger said.
He and new roommate Daniel Morris were starting new jobs on Monday.
Morris just arrived from Michigan.
"His boss had been calling him to come work before we could even get him," Morris said.
Best friends since 7th grade, Enfinger knew Morris as well as someone can.
That night, he says the only tension was a family disagreement that Morris was not involved in, and helped settle.
There has been intense speculation on whether Morris was on drugs, drunk, or suicidal.
Enfinger said he was not drunk or on drugs, and there were no indications he was suicidal.
"Not that he had ever let on to me," Enfinger said. "And I was his best friend."
But at around 2 a.m. Sunday, the beginning of the end came.
"He literally walked in the back door, and made a joke to me and we all giggled and we thought he was going to the bathroom," Enfinger recalled. "It was just something like ‘screw you guys' or ‘I love you guys.' It was just something that we would joke about."
Enfinger says it was nothing to be alarmed at.
"He wasn't upset, he was smiling, he was happy. That's the last memory I have of my brother, is the smile on his face when he left," Enfinger said.
Next thing they knew, the engine of Enfinger's white SUV was starting.
Then, he was watching, and running after Danny, who peeled out so fast a Enfinger saw a tire lift when he made a turn.
"My feet were tender and bleeding from trying to chase him," said Enfinger. "By the time I was able to get into shouting distance, with the people on my property, all I cloud get out was 'call the cops.' "
Then Morris was spotted on the highway.
Then a ball of fire and five deaths.
Enfinger started asking the same questions as everyone else.
"I would love to know why. Why choose that? Why the wrong way? Why why why? I have no clue."
He also offered condolences to the victims' families.
"I know from the reports that they were very good, well-respected young men, and they had a very good head on their shoulders, and they were going somewhere," said Enfinger. "I offer my deepest, heartfelt condolences to the family. I could never understand how that feels, that's just horrible."
"Have you rectified in your mind that you did all you could do?" we asked.
"A million times. Yes sir," he said.
Enfinger has retained an attorney, John Hackworth, saying representation gives him peace of mind.
