The manhunt for 18-year-old Dalton Hayes and his 13-year-old girlfriend, Cheyenne Phillips, dubbed the "teenage Bonnie and Clyde" by some, stretched across several states in the Southeast, but it ended with their capture Sunday in Florida as new details emerge about their relationship, reports CBS News correspondent Vicente Arenas.
Hayes posted on his Facebook that the two were engaged. Hayes' mother said he bought her an engagement ring and that Phillips even claimed she was pregnant.
"When she first told my son that she was pregnant, she shouldn't have been but three weeks pregnant or something, and she sent him an ultrasound picture via a text -- and that was not her pregnancy picture," Hayes' mother Tammy Martin said.
Hayes was arrested and charged with being a fugitive from justice. Phillips was placed in the care of children's services. The girl, who portrayed herself as being 19 years old, is actually only 13.
The long arm of the law finally caught up with Hayes and Phillips when U.S. Marshals received a tip they were in area. Shortly after midnight on Sunday, the pair was found asleep inside a Toyota truck that had been stolen in Georgia.
"The Bay County Sheriff's Office, Panama City Police, Panama City Beach Police Department, surrounded the vehicle and gave them absolutely no way out," Grayson County Sheriff Norman Chaffins said.
Last week, the pair were spotted inside a Walmart in South Carolina. Authorities were worried about their increasing brazenness. The last truck they allegedly stole contained two guns.
The couple vanished earlier this month from Kentucky, shortly before Hayes was due in court for burglary and theft charges. Phillips told her mother about their plans.
"She said, 'We're just going to run' and I said, 'No, you don't need to do this,' because Dalton was supposed to be in court that Monday morning," Phillips' mother Sherry Peters said.
Their alleged crime spree spanned five Southern states and their exploits prompted comparisons to fugitive lovebirds Bonnie Parker and Clyde Barrow.
But unlike those murderous fugitives, Hayes and Phillips are only suspected of using forged checks and stealing vehicles while on the run.
The sheriff of Grayson County, Kentucky, told "CBS This Morning" that the couple will have a court hearing either Tuesday or Wednesday in Florida. By the end of the week, he expects them back in Kentucky to face numerous felony charges, after extradition papers are signed.
