Baker police arrested a 32-year-old mother of three Saturday and accused her of leaving her three children — ages 4 months, 20 months and 7 years old — inside a vehicle with no air conditioning and the windows rolled up for about 30-45 minutes.

A witness told officers at the Baker Wal-Mart on Plank Road that the mother, Tesha Thomas Cobb, arrived in a 2012 Infinity SUV at about the same time as the witness, according to a Baker police report. The witness said Cobb went into the store and left the children in the car, according to the report.

The witness said she walked out of the store some time later, went to a nearby pizzeria and then walked back to the Infinity to find the children still inside.

She estimated it was about 30-45 minutes from the time she first saw the children inside the SUV to the time she called the police after leaving the pizzeria, the report says.

Officers noted that the 4-month-old child had been screaming and the baby’s diaper was soaked.

Officers contacted Cobb inside Wal-Mart. She said she had only been inside the store for about 15 minutes, the report says.

Cobb called her sister to pick up the children.

Police booked Cobb, 4310 Felix Road, Ethel, into Parish Prison on three counts of child desertion. Officers did note on the report that Cobb had no criminal history.
