"We have to be there whenever we can," said the girl's great uncle, Michael Dolphin. "I'm really sorry to say we could've done better by Tioni."
Theus died of a gunshot wound to the neck, according to officials. She was last seen Jan. 7 in Compton and had told her father she was meeting a friend to go to a party.
Drivers reported seeing her body dumped on the ramp's shoulder off the 110 Freeway the next morning, according to the California Highway Patrol.
"I lost a piece of my soul it feels like," said the teen's father, Darien Jackson. "This is the second kid I've lost in four-and-a-half years."
The 16-year-old was reportedly a victim of human trafficking, according to the Los Angeles County District Attorney's Office.
Meanwhile, community leaders and her family have stressed that Theus' death deserves widespread attention.
"For too long, many young African American girls - babies, 16-year-olds - have been snatched in the human trafficking and very little is being said, and it's time for that to stop," said community activist Robert Sausedo.
Investigators tell Eyewitness News as of Thursday, they do not have any new leads. Anyone with information is urged to contact the California Highway Patrol.
