JACKSONVILLE, Fla. -- A 24-year-old man is facing murder charges after a toddler died from shaken baby syndrome this weekend.

Todd Howell is the live in boyfriend of 22-month-old Kyleann Burress's mom.

Howell reportedly took Burress's mother, Stephanie Green, to work around 7:00 a.m. Saturday. They left the child at home sleeping in a playpen.

Howell first denied harming the toddler intentionally or by accident. Then he said he wanted to come clean.

He admitted that when he came back from dropping Green off at work, he was changing Burress's diaper on the sofa. That's when he reportedly dropped the child. He then says he vigorously shook the child while trying to revive her.

DCF has been notified and it will be up to the State Attorney's Office to prosecute Howell.
