HOUSTON -

A Houston woman is facing a serious charge after her 6-year-old daughter was found walking alone near a busy roadway.

According to court documents, a witness called police on May 1 after seeing the girl attempting to cross the freeway feeder alone at Sam Houston Parkway and Vickery Drive. The responding officer found the girl walking southbound on Vickery.

The girl told the officer she had just walked to the gas station to get a soda. The officer said the girl stated that her mother, Jolisa Peterson, let her leave the house.

Court documents state the girl said she did not go to school that day due to her mother not waking up because she was "having sex with her boyfriend."

According to court documents, the officer spoke with the clerk at the gas station. He told the officer the girl had been in the store twice that day with adult supervision.

According to court documents, the girl was able to show the officer her apartment complex. She was not able to tell him which apartment, so the officer went to the leasing office.

The manager told the officer she has found the girl walking around the complex unsupervised with a younger sibling multiple times. The manager escorted the officer to the girl's apartment. After several knocks, Peterson opened the door.

According to court documents, Peterson denied knowing her daughter had left the residence. The manager pointed out that the door was locked, which someone would have had to do from inside of the apartment or with a key on the outside.

Peterson, 22, was arrested and charged with endangering a child.
