An Irving woman remained jailed Thursday under a suicide watch after allegedly strangling her two young children with a wire.
A Dallas County sheriff's spokeswoman said Thursday that 30-year-old Saiqa Akhter of Irving is being kept under a close 24-hour watch in the county jail. She received a psychiatric evaluation when she was booked into jail.
Akhter is charged with two counts of capital murder in the deaths of her 5-year-old son, Zain Akhter, and her 2-year-old daughter, Faryaal Akhter, who died Tuesday night.
Faryaal was buried Thursday in Richardson, one day after her brother's burial.
"It is a hard time for us -- you can imagine," said Wasimul Haque, the children's uncle. "And I can't explain why inside what's happening now."
According to a recording, Akhter told a 911 operator that she killed the children because they were autistic and she wanted "normal kids."
Haque said only Zain had autism.
"I lost everything -- my babies -- but I don't want to lose my niece," Haque said. "She must see that psychiatrist right away, because she needs medical help right now."
Family members said Akhter is confused about what happened to her children.
"She says, 'I didn't did it. How did this happen?'" Haque said.
Bond for Akhter has been set at $1 million.
