Mom's Boyfriend Charged In Pittsburgh Baby's Death PITTSBURGH -- Police said a man accused of assaulting a 10-month-old girl last week has been charged with homicide in the baby's death. Da'Niyah Marie Jackson, of Troy Hill, was assaulted last week in her Herman Street home, police said. She died Saturday at Children's Hospital. The Allegheny County medical examiner ruled the death of Da'Niyah a homicide. The examiner said the autopsy showed the baby died of multi-system organ failure and blunt force trauma to the abdomen. The mother told police she left the baby with her boyfriend, Clinton Smith, on Thursday morning when she went to her waitressing job. Smith was also caring for his 2-year-old son. Smith, 30, was charged with homicide, rape, aggravated assault, among other charges. The mother found the baby unresponsive when she returned home at about 9:30 p.m. and called paramedics. The baby had severe bruises on her face, arms and legs, as well as a bite mark on her chest, police said. Doctors told police she had also been sexually assaulted. "It was tragic," said Assistant Chief Maurita Bryant of the Pittsburgh Police Department. "As police officers, we all can see the ugly side of society and in this case, what happened to Dania absolutely tears our hearts." A preliminary hearing for Smith was scheduled for Wednesday. He was awaiting trial on an unrelated June charge of simple assault, court records show. In a separate September 2006 case, a woman who has two young children with Smith was granted a protection-from-abuse order against him after she said he attacked her and their daughter.
