A young father from Detroit was exonerated after being accused of murdering and sexually assaulting his 8-month-old infant daughter, who died April 23. James Lee Saltmarshall, 22, faced charges of felony murder, first-degree child abuse and first-degree criminal sexual conduct. On Thursday, all charges against Saltmarshall were dropped “in the best interest of justice,” Wayne County Prosecutor Kym Worthy’s office said in a statement Thursday.
