Cheyenne Phillips, 13, and her boyfriend, 18-year-old Dalton Hayes — who are two missing Kentucky teens characterized as “brazen” and “dangerous” — are reportedly on the run and suspected of a crime spree that spans several states across the South.

Grayson County, Georgia, Sheriff Norman Chaffins said Dalton Hayes and Cheyenne Phillips may be staying in camps or homeless shelters and may be in possession of weapons that were in one of the vehicles they allegedly stole.

“I think it started as a game or something funny,” Chaffins said. “So far, they’ve committed crimes in four states. We don’t think it’s funny.”

The modern-day “Bonnie and Clyde” teens were reported missing on Jan. 3 from Louisville, Kentucky. They’re accused of stealing a neighbor’s red Toyota pickup. They reportedly dumped the pickup in Georgia before stealing a silver Toyota Tundra that had two handguns in the vehicle.

The teens are wanted on at least two counts of auto theft. Dalton Hayes is also wanted on charges of custodial interference for enticing Cheyenne Phillips from her home.

Tammy Martin, Dalton Hayes’ mother, told reporters that her son and Cheyenne Phillips had only just started dating. She said she didn’t know Cheyenne Phillips was only 13.

Hayes apparently texted her on Jan. 6: “Mommy, don’t worry. I’m fine, okay — plenty of money and food. Love you, good night, sweet dreams.”

The teens’ parents are desperate for them to come home and are begging them to turn themselves in.

“Dalton, Cheyenne just turn yourselves in. You’ve got family here that cares about you and loves you and we are all hurting just for them to turn themselves in,” said Sherry Peters, mother of Cheyenne Phillips.

“There’s enough charges that are going to be filed on them as it is — they need to come home,” said Martin. “Everyone is just worried sick about Dalton and Cheyenne about them getting home. We just want them safe.”
