DETROIT -- A 6-year-old boy's 911 call for help was thought to be a prank, but the call was real and the boy's mother died, Local 4 reported.

Robert Turner (pictured) called 911 to get help for his mother, Sherel Turner, 46, whom he found lying unconscious on the kitchen floor of their Detroit apartment in February, the station reported.

"Then I had felt her tummy. She wasn't breathing. Then I had called 911," said Robert. "I told them to send an emergency truck right now."

911 Operator: "911. What's the problem?"

Robert: "My mom has passed out."

The 911 operator, however, did not take him seriously and told him to stop playing on the phone, the station reported.

911 Operator: "Where's the grownups at?"

Robert: (Inaudible)

911 Operator: "Let me speak to her before I send the police over there."

"I tried to tell them she wouldn't talk," said Robert to Local 4.

Robert: (Inaudible)

911 Operator: "I don't care. You shouldn't be playing on the phone. Now put her on the phone before I send the police out there to knock on the door and you gonna be in trouble."

Robert: "Ugh!" (Hangs up.)

Kimberly Harris, the union president of AFSCME Local 1023, said more than a quarter of phone calls received by 911 operators are prank calls. She also said that everybody does not express their pain or emergencies the same way.

"That operator could have had five prank calls. Kids calling in prior to that call. And please, don't think that I am trying to make an excuse. That was a tragedy," said Harris.

Officials said the 911 operator will be disciplined, but because of her years of service she will not be fired.

"I know that operator. I know that she is a very good operator," said Harris. "She is very thorough.

Robert said every time someone talks about his mother, he starts crying.

Police continue to investigate.
