LEITCHFIELD, Ky. — Police say unless they surrender, the “outcome is not going to be good” for two teenage sweethearts who’ve blazed a trail of crime across the South, leaving in their wake a string of stolen vehicles and pilfered checks while stirring concern about their increasingly bold behavior.

The 18-year-old and his 13-year-old girlfriend — who had apparently convinced the boy and his family that she was 19 — have so far eluded capture and are now believed to be cruising around in a stolen truck with two guns.

Dalton Hayes and Cheyenne Phillips vanished Jan. 3 from their small hometown in western Kentucky. Since then, authorities believe the two have traveled to South Carolina and Georgia.’

The couple had been dating for about three months.
