KLAS-TV reports that Las Vegas police arrested 28-year-old Cork Wood on Wednesday and added the murder charge on Thursday. He was originally charged with child abuse and neglect in the first degree.
The Clark County coroner's office says La-Rayah Davis, 5, died as a result of child abuse.
The police have also accused Amy Taylor of child abuse and neglect.
The connection between the three is not known and it is not clear if the suspects have lawyers or will be appointed as legal representatives in a pending court appearance.
Wood played in college at Notre Dame and spent time in the NFL with Houston, New England and Buffalo. He was recently released by Montreal Alouettes of the Canadian Football League in 2017.
