Authorities revealed new details about the death of a 2-year-old Michigan girl as they announced federal kidnapping charges against her mothers ex-boyfriend Friday.

The body of Wynter Cole Smith was found in a Detroit alleyway Wednesday after she was allegedly taken from her mothers Lansing apartment earlier in the week, prompting an intense search. On Friday, Rashad Trice, 26, was charged with kidnapping a minor and kidnapping resulting in death, according to a federal complaint obtained by HuffPost. He was already facing eight other charges, including criminal sexual conduct, assault with intent to murder, home invasion and unlawful imprisonment.

The allegations in this case are heart-wrenching, said Mark Totten, the U.S. attorney for the Western District of Michigan, in a statement announcing the charges. My thoughts are very much with Wynters family, as we were all praying for her safe return home.
