The parents of a 22-day-old baby found starved to death in Florida have been charged with first-degree murder, police said on Tuesday, accusing them of neglecting the suffering infant.

Ruby Stephens, 23, and Roy Stephens, 48, of Indiana were visiting relatives in central Florida on Dec. 23 when they called for emergency help after discovering the baby was unresponsive in their car, according to Lakeland Police.

Betsey Kee Stephens was declared dead at the hospital.
