Also arrested was 34-year-old Connie Nelston -- said to be Linkenhoker's girlfriend. Nelston was charged for interfering with a police investigation and filing a false report.
Both were behind bars Sunday without bond.
Investigators believe Linkhoker intentionally hit 15-year-old Charli Rae Gore as she was walking home after a party just after midnight Saturday.
Her body was found in a ditch a short distance away.
Liberty County Sheriff's Office deputies said they received several anonymous tips leading them to the car they say was used to kill Gore.
Gore was a sophomore in high school.
The girl's family friend released a statement to the media Sunday.
"The family is deeply saddened and devastated by the tragic and sudden death of their beloved daughter, Charli R. Gore," it read. "We appreciate the concern and prayers from all friends and neighbors."
The statement also extended gratitude to the police and witnesses for the quick response and capture of the suspects.
"Thank you all….please pray for our family," it read.
