Young couple Frances and Darren Jenkinson of Glasgow, Scotland, were happy and attentive parents of 8 week-week old baby boy Aaron when tragedy struck. After 3 bouts of difficulty breathing, their baby boy had irreversible brain damage and was taken off life support. This loss was especially difficult for Frances who was only 18 years old. After taking time to grieve and heal, the couple had a second child in 1999: Jacob. But at only 3 weeks of age, Jacob met the same fate as Aaron had. His death brought suspicion. Further investigation would reveal the unimaginable.
