Authorities Thursday announced charges against a Dallas woman following the drowning deaths Sunday of two 5-year-old girls—one of which was her granddaughter.

Marta Sonia Corvi, 58, was arrested by the Dallas Police Department and charged with two counts of reckless conduct. She was the housekeeper at the Vista Lakes subdivision home in Dallas at which Sophia Juarez, who resided in the home, and Mia Penoyer of Grayson drowned in the home’s in-ground pool. Corvi is also Penoyer’s grandmother.

Corvi's arrest was announced by the Paulding County Sheriff's Office, which is assisting Dallas Police with the release of information in the case.

Sgt. Bill Gorman of the Dallas Police Department told Dallas-Hiram Patch Monday that the girls had been found in the pool fully clothed Sunday afternoon. Officials believe they went into the pool sometime during a 45-minute time span when Corvi was on the phone.

Corvi as of Thursday afternoon was being held in the Paulding County Detention Center awaiting bond. Dallas Police previously withheld her name as she had been taken to WellStar Paulding Hospital for evaluation following the incident.

The girls were at least the second and third youth drowning deaths in Paulding within the past year. In August, a 22-month-old boy died two days after being found in his family’s aboveground pool unresponsive and not breathing.

In June of last year, a Dallas woman nearly lost her young daughter after the girl climbed into a neighbor’s aboveground pool. The 2-year-old’s life was saved by a repairman who was at her mother’s house to fix the air conditioner.
