The St. Lucie County Sheriff's Office said Jayme Beall, 30, told them she stuffed her sons' backpacks full of clothes and sent them outside around 7 p.m. Monday at the Pineview Mobile Home Park in Fort Pierce because she was angry at the 9-year-old for swearing, TCPalm.com reported Thursday.
Beall, who called 911 when she was unable to locate the boys about 20 minutes later, told deputies the 13-year-old has run away before and has a history of violence toward her.
Deputies said the boys were eventually found at their great-grandmother's house in Boynton Beach, more than 70 miles away.
Investigators did not say how the boys made the trip to Boynton Beach.
Beall was arrested on a felony child abuse charge and taken to the St. Lucie County Jail.
