Boyfriend Allegedly Punched, Stomped Girlfriend's Child To Death

A young Texas couple have been arrested in the murder of an 18-month-old child who was brutally abused before being stomped to death and buried under a bridge wrapped in a blanket, police said.

Joshua Beard, 20, and Alexis Botello, 17, had only been dating for a few months prior to the death of Botello's daughter, Tylea Moore, on July 4.

In an Arlington, Texas, police affidavit obtained by The Huffington Post, officers said that Beard had called the toddler a "little demon" while punching her and that he also abused Botello when she attempted to stop him.

"Botello said Beard was pushing and yelling at Tylea," the report reads. "Botello kept yelling at him to stop, that she was just a baby and didn't understand. Beard then started yelling and hitting Botello."

The alleged abuse only grew worse from there. According to the report:Botello told police that Beard began punching her as she tried to help her child. Beard allegedly then took the little girl and slammed her down on the bed so hard that she bounced off and landed on the ground. He continued to hit the child with closed fists, police said.

Beard then began stomping on Tylea's stomach .

While Tylea's grandfather was desperately searching for answers, police were gathering evidence.

Police said that after Tylea died, Beard and Botello went to a Walmart where they bought gloves and two shovels. Investigators said the couple was easily identified leaving the store from surveillance video.

The couple then drove to a remote area, dug a grave under a bridge, wrapped the little girl in a small blue blanket and buried her, according to the police report.ch "over and over again," according to the police report. When Botello tried to stop him, he allegedly hit and choked her.

The child died a short time later, police said.  

It's just too sad that a mother will help cover up her own childs murder.
