Images of Caitlyn Frisina, 17, and coach Rian Rodriguez, 27, show the pair traveling through the Carolinas following their disappearance on Sunday

Authorities have released surveillance images they say show a 17-year-old Florida girl on the run with a 27-year-old soccer coach from her high school, both of whom have been missing since Sunday.

The images made public Wednesday track Caitlyn Frisina and Rian Rodriguez as they appeared to be traveling northward through the Carolinas after the teen allegedly slipped out her bedroom window in Fort White, Florida, late Saturday night or early Sunday morning, according to an incident report from the Columbia County Sheriff’s Office.

Caitlyn left behind her cell phone that she’d wiped clean with a factory reset, and detectives have confirmed she withdrew $200 at 1:28 a.m. Sunday from an ATM in St. Marys, Georgia, about 115 miles north of her home.

Around 7:30 a.m. that same day, the newly released surveillance images show the red Mercury Sable — with the Florida tag Z04CSC — that the two are believed to be traveling in parked outside a Bobopo Food Store store in Hardeeville, South Carolina.

Ninety minutes later, another surveillance video image shows the pair together at a Pilot gas station in Saint George, South Carolina. At 3:47 p.m., the pair turned up again on surveillance video at a pawn shop in Fayetteville, North Carolina.

“We have no indication that Rian has kidnapped her or is holding her against her will, and we do not believe that he will harm her,” sheriff’s spokesman Sgt. Murray Smith tells PEOPLE. “But she is still a juvenile and needs to be home with her family.”

Sheriff Mark Hunter echoed those statements at a news conference Wednesday, saying, “She’s with a person who is 10 years her senior in a supervisory capacity over her as a coach,” reports CBSNews.com.

“She is legally a juvenile. Although she’s 17 years old, she’s still unable to consent by law,” he said. “That’s our concern, and our concern of course is that we don’t know she’s OK.”

Smith says that Frisina’s father has relatives in New York and Rodriguez has relatives in Canada and possibly Pennsylvania as well.

The incident report states “there may be a relationship” between the missing teen and the coach at her Fort White High School, based upon a text message Caitlyn sent to a friend and which was retrieved by investigators.

“There wasn’t any indication that they had a relationship up until they left,” Smith says. “Once they left and everybody was interviewed, there still was no smoking gun that they were in a relationship.”

“But it is our belief that one or both of them began to have some type of feelings that they wanted to be together, so that’s why they left,” he says.

The Columbia County School District, which has since suspended Rodriguez while the investigation is proceeding, previously identified Rodriguez as head coach of the high school boys’ soccer team. Sheriff’s Detective Capt. Katina Dicks previously told PEOPLE that Rodriguez also worked as an assistant coach on Caitlyn’s girls soccer team.

Hunter repeated the statement by Caitlyn’s parents that Rodriguez was considered a family friend, and added that Caitlyn’s father, Ward Frisina, also coaches the boys’ soccer team.

The sheriff said Rodriguez could face criminal charges of interference with child custody or more.
