A Texas couple allegedly tried to dissolve their 2-year-old daughter’s body in a bucket of acid after she drowned while bathing unsupervised, the Laredo Morning Times reports.

Prosecutors have charged Gerardo Zavala-Loredo, 32, and Monica Yvonne Dominguez, 37, with abuse of a human corpse and evidence tampering in connection with the case. Both are felonies under Texas state law. Dominguez also faces two counts of child endangerment.

Dominguez told investigators that her kids were taking a bath unsupervised in their Laredo apartment on Thursday afternoon when the 2-year-old girl, Rebecka Zavala, drowned.

Dominguez then asked her husband for help with disposing the body, according to Webb County District Attorney Isidro Alaniz.

Alaniz said the girl’s remains would be examined to assess whether there are any “injuries consistent with a murder.”

“We need to wait to see what the science tells us,” Alaniz told Laredo Morning Times. “Right now there’s more questions than answers.”

Police searched the apartment around 5 p.m. Thursday after being tipped off by a neighbor. Officers found the girl’s remains in a 5-gallon bucket, which appeared to contain acid, inside a bedroom closet.

Both parents remain in jail, with Zavala under a $125,000 bond and Dominguez under a $175,000 bond.

In addition to Rebecka, the couple has four children, ages ranging from 1 to 11, who have been removed from the home by child protective services, according to the newspaper.

Laredo is in southern Texas along the Mexican border.
