Houston police arrested a mother who allegedly left her 3-month-old son unattended in a car early Sunday while she patronized a southeast Houston bar, Harris County prosecutors said.

Amy Dawn Cooney, 31, has been charged with felony endangering a child, court records show. A judge set a $2,000 bail for the suspect, who was being held Monday at the Harris County Jail.

Investigators said Cooney was at Texas Joe's Pub at 11045 Fuqua St. when she struck up a conversation with another bar patron about 3:30 a.m., HPD spokesman Kese Smith said.

"She (suspect) started talking to another woman as if she knew her," Smith said. "She told the witness (woman) that she was there with her 3-month old son."

When the woman asked where the baby was, Cooney told her that he was in a vehicle, according to an arrest warrant filed in the case. The witness asked Cooney to show her the baby, and she suspect led the woman to the vehicle and opened the door.

The woman quickly grabbed the infant and took him to a Harris County sheriff's deputy who was working part-time security at the club, investigators said.

The deputy called Houston police, who arrested the mom. The baby, who was unharmed, was released to the care of his grandmother, investigators said.
