Maria texted her dad saying someone was knocking at the door

On Aug. 12, Maria's father, Carmelo Gonzalez, called police saying his daughter wasn’t breathing, police said Tuesday. She was pronounced dead at the scene.

Police said Maria was home alone after her dad left for work around 9:45 a.m. Police said the last message Carmelo received from his daughter was her saying someone was knocking at the door.

Carmelo told local station KHOU that he told his daughter not to open the door, and she said she wouldn’t. After that, he said he never heard from her again, the station reported. 

Soon after, Carmelo asked his brother and sister-in-law, who also live in the apartment complex, to check on her, The Associated Press reported. They found the front door unlocked and things out of place, but they didn’t find Maria, AP reported.

Police said Carmelo came home from work and found his daughter's body hidden underneath her bed in a plastic trash bag that was placed inside a laundry basket. 

The medical examiner said Maria died as a result of asphyxia from being strangled. She was also sexually assaulted, the investigation found.
