"They have surviving children that they are responsible for, so their eggs are all in one basket, hoping they can stay on a probationary disposition so they can be there for their children," Griffen said.
Had they been found guilty at trial, Griffen said the Rawlings would have been given mandatory prison sentences.
A message left with an assistant to Lacey Rawlings' attorney was not immediately returned last Friday.
The couple, along with seven other family members, were riding a military-style truck near Tonto Basin, about 145km northeast of Phoenix, on November 29, 2019. A major storm had brought 50mm of rain to the area. Despite barricades and signs indicating the crossing was closed, they attempted to traverse Tonto Creek.
The truck ended up stuck. The couple and four other children were able to climb out and be rescued by helicopter. Their 6-year-old daughter, Willa, 5-year-old son, Colby, and 5-year-old niece, Austin, remained in the vehicle, which got swept away.
Colby and Austin's bodies were found the next day. Willa's body was recovered two weeks later 32km from where she went missing.
Their deaths spurred the award last year of a USD$21 million federal grant to Gila County to build a bridge over Tonto Creek. Eight people have died trying to cross the creek during flooding since 1995, state lawmakers said.
