DALLAS (CBS11) — A Northeast Dallas community is trying to understand the unthinkable – a mother accused of poisoning her young son.

Paw Eh, 31, faces an attempted capital murder charge.

On Saturday, police got a 911 call to the Newport Landing apartments from a relative of Eh.

First responders rushed a 4-year-old boy to the hospital in critical condition.

Dallas police say Eh forced her son to ingest poison. Police also say she tried, unsuccessfully, to force her 7-year-old and 12-year-old to do the same.

A friend of the family says the older two children realized what was happening and ran to their grandmother’s apartment, also in the same community.

The apartment complex is made up of mainly immigrant families, including Eh’s family, who neighbors say is originally from Myanmar.

“She treated her children well, when I met her,” said Nay Thaw, a friend of the family.

He was one of several neighbors who expressed concerns for Eh’s mental health.

“I think it was a mental breakdown,” Thaw said.

“Some people say the mother is not 100 percent,” said Thang Awi, another neighbor who knew the family.

A spokesperson for Child Protective Services says a preliminary records check showed no history with Eh’s family and CPS.

No criminal records for Paw Eh show up in a background search.

Neighbor Sharl Nie says she has reason to believe Eh struggled with mental health issues. She would sometimes accompany Eh to see a doctor, Nie says, to translate from her native Burmese language to English.

“All she talked about was she couldn’t sleep at night, or she was thinking about suicide,” Nie said.

It saddened her to hear of the child injured and the mother’s arrest.

“She’s been sick for a long time. I don’t know about medicines, but she was taking some from the doctor,” Nie said.

A check of the Dallas County Jail log shows Paw Eh remained in jail Sunday night, on $500,000 bond.
