A lawyer for a Las Vegas woman is calling for criminal charges against hospital officials who he says ignored his client in the emergency room so long that she went home and gave birth to a premature baby who died.

Attorney Jacob Hafter on Tuesday accused University Medical Center administrators and nursing officials of criminal neglect for failing to treat 25-year-old Roshunda Abney. He also accused them of involuntary manslaughter in the death of Abney's premature daughter.

Hafter says he doesn't trust the Clark County district attorney to prosecute because the public hospital is owned by the county.

There was no immediate response Tuesday from state Attorney General Catherine Cortez Masto.

A UMC spokesman says the hospital is investigating the Nov. 30 incident, and cooperating with ongoing probes by outside agencies.
