HOUSTON (NEXSTAR) — A Houston mother was charged after authorities allege she placed her 13-year-old son in the trunk of her car to isolate him after he tested positive for COVID-19, then took him to a drive-thru testing site.

The 41-year-old is charged with endangering a child after authorities allege her son was found on Monday in her car’s trunk at a testing site for the Cypress-Fairbanks school district in northwest Houston.

The woman is a teacher with the school district, which says the child was not harmed.

The mother told a district official that she put her son in the trunk to prevent her from getting exposed to COVID-19 while taking him for additional testing.

The official then asked to see her son, according to the Houston Chronicle, telling her he couldn’t be tested for COVID-19 until he was in the backseat. She opened the trunk to show the child lying inside, according to court documents.

She then left to find a police officer and, by the time she returned, the boy was sitting in the backseat.

The school district confirmed to the paper that the mother is now on administrative leave.
