(CNN) -- An Irving, Texas, woman told a 911 operator that she strangled her two young children Monday because they were autistic, according to a recording of the call.
Saiqa Akhter, 30, has been charged with a single count of capital murder in the deaths of her 2-year-old daughter and 5-year-old son, police said.
Dallas County Police spokeswoman Jamille Bradfield said the single count covered a child under 5 and would probably be changed either to include multiple victims or to add a count.
"I'm just not sure which direction the police will go yet," she said.
A woman who identified herself as Akhter called police Monday evening and said she first tried to kill her children with bathroom cleaner, but they would not drink it. She told the 911 operator that she then strangled them with a wire and that they were on her bed.
Police and paramedics tried to resuscitate the children, but Zain Akhter died at the hospital Monday, and his younger sister, Faryaal Akhter, died at the hospital Tuesday evening, according to authorities.
On the tape, the woman tells the operator, "I killed them. I killed both of them. I killed my both kids. ... They are not doing anything. They are just blue. They are not taking any breaths. Their heart is not beating".
The operator asks her what happened.
