A South Carolina man accused of driving under the influence of drugs and alcohol had "no recollection" of a crash that left a high school student dead, his attorney told a judge during a bond hearing Friday morning.

Carter Owen, 27, of Pelzer, is charged with felony DUI in the crash that killed Trinity Harrison, an 18-year-old who was riding home with a relative after her senior prom night at Ware Shoals High School. Owen crossed several lanes and struck Harrison head-on along U.S. 25 in Greenville County on April 6.

Circuit Judge Perry Gravely set a $25,000 surety bond for Owen and ordered him to a home monitoring program if he does post bond.

Defense attorney Randall Chambers called the incident a set of "tragic circumstances."

"My client has absolutely no recollection of this accident," Chambers said in court Friday morning. "He woke up and was told what had happened and he's devastated by the situation."

Owen, appearing in court via a video monitor broadcast from the Greenville County jail, wiped tears from his eyes and kept his head down during the hearing. His hands remained folded on top of a podium he stood behind.

Assistant Solicitor Sylvia Harrison said in court that the case involves a "victim who did everything right" and a driver who did everything wrong.

"Mr. Owen was driving completely erratically during this time," she said.

She said blood and urine taken four hours after the wreck showed Owen had a blood alcohol content level of .17 percent and had methamphetamine, cocaine and marijuana in his system.

"Driving while under such tremendous amounts of illegal drugs and alcohol make him a danger to the community to get him back out there under any circumstances," Sylvia Harrison said.

Trinity Harrison wore a blue dress to her prom night April 6. Photos from the evening were shared across social media and used for a vigil at the auditorium at Ware Shoals High School.

At Ware Shoals' senior graduation, Trinity Harrison's parents were handed a posthumous diploma on their daughter's behalf.

Brandon Harrison, Trinity Harrison's father, is still grappling with the reality of his daughter's death.

"She should be here. Trin should be here. Just like at graduation, she should have been there. It hurts so bad, man," the father told The Greenville News outside the courtroom Friday. "I'm just trying to do it one day at a time, you know. It's hard because we usually would text each other even if we don't see each other, except now I can't do that."

Brandon Harrison wore a pendant necklace to court that contained a picture of him and Trinity posing together. A good friend had it made for him after her death, he said, wiping tears from his face.

"Is he truly sorry?" Brandon Harrison said of Owen. "His defense attorney is saying something about how he can't remember. I don't buy that but OK. Could you be that drunk though to cross four lanes?"

Brandon Harrison said his daughter would want him to forgive Owen and continue to live a meaningful life.

"She would want me to forgive him," the father said. "I know because that's the type of person she is. She'd want me to forgive him and continue to move on and try to live right."
