Detroit ? Attorney Geoffrey Fieger said Sunday on the “Today” show that he believes a 46-year-old Detroit woman would have lived had a 911 emergency dispatcher taken seriously a call for help from her then-5-year-old son.

He said he plans to file a wrongful death lawsuit on behalf of the family today.

On Feb. 20, Robert Turner, now 6, called 911 twice as his mother, Sherrill Turner, lay dying from complications of an enlarged heart in their Detroit apartment. A dispatcher once hung up on the boy; a recording of the call indicates the dispatcher hung up after saying she would send police to the home. They did not arrive.

When Robert called again about three hours later, a different dispatcher scolded him for playing with the telephone and said he would be in trouble when the police showed up.

A police squad car eventually responded to the home, but it was too late for Sherrill Turner. It was not clear at what point she died.
