Romoutar was 19 when he was arrested in connection with the Dec. 6, 2016, death of Wright.
Wright’s family previously told WSB-TV that the teenager went to Ramoutar’s home in Covington the night before her body was found.
“We were sitting on the bed, laughing, joking about things that were starting to look up for us,” Melinda Wright said. “She said, ‘Bye. I love you. I’ll be back.’”
Newton deputies went to the residence after one of Romoutar’s relatives called 911. The family member, prosecutors said, told authorities Romoutar reached out and said he had killed his girlfriend.
Deputies found him behind the house, and Wright was found dead inside, according to prosecutors. He confessed to law enforcement, too, they said. An autopsy by the Georgia Bureau of Investigation found that Wright died from strangulation.
It’s not clear why Romoutar killed Wright. There were no signs of issues between the couple, Wright’s family said.
After accepting Romoutar's guilty plea, Superior Court Judge Samuel Ozburn handed down the sentence.
