Babysitter arrested for murdering three-year-old boy in Melbourne.

The babysitter also left the a note saying he accidentally drowned in the bathtub.

However, the autopsy revealed that the baby was beaten up.

On June 11,Joshua Manns, 25, called 3-year-old Jameson Nance’s mother while she was at work, he told her he had drowned in the bathtub. But when she got back to her apartment in West Melbourne.

She found that Manns was nowhere to be seen and had never called for medical assistance. 

Instead, authorities say, he left her a handwritten note saying he had a seizure while Jameson was in the tub, resulting in him drowning.

Authorities said he wrote in the letter: ‘no one would believe him and he did not want to spend his life in prison for something he did not do.’

The medical examiner, though, did not find any evidence that the young boy had drowned, saying he actually suffered from battered-child syndrome, suffering from weeks-old injuries, including a broken rib, stab wounds to the head and brain swelling.

Jameson had also suffered a broken leg last March, and the Florida Department of Children and Family Services investigated another broken leg he had when he was just 1-year-old.

And shortly before he died, the department had gone to his daycare to investigate ‘suspicious injuries,’ like burn marks on his arm.
