DALLAS —  The case involving the 3-year-old Dallas-area girl, first reported missing and later found dead, may lead to a new law. 

The proposed "Sherin's Law" would make it a felony to leave a child home alone and not to report a missing child within a few hours.

Adopted father, Wesley Mathews, has been charged with capital murder in the 2017 death of his 3-year-old daughter adopted from India, Sherin Mathews.

Richardson Police told WFAA that Wesley had told investigators they left for dinner the night prior to her disappearance on the evening of Oct. 6, 2017. Wesley, his wife, Sini, and their biological daughter had gone to dinner on Friday night.

At 3 a.m. the following morning, Wesley told police he had “physically assisted” Sherin with drinking her milk, and then watched as she choked to death before placing her body outside the home. The little girl’s body was found three weeks later.

A grand jury found that Wesley had used a deadly weapon to kill Sherin. He's has been charged with capital murder, and faces the death penalty.

Sini, adopted mother of Sherin, has been charged with abandoning a child, a felony offense which carries a sentence of two to 20 years.

According to WFAA, the proposal is being led by Reena Bana and Shanna Poteet. Both have taken a lot of interest in the Sherin Mathews case and are working with family and criminal law attorney Bilal Khaleeq. 

"No children under 9 or 10 years old need to be left unaccompanied at home," said Poteet.

Ages nine, ten, and even 12, have been mentioned as minimum age requirements for the law, according to Khaleeq.

As it stands, Texas laws don't dictate a minimum age for a child to be left alone.

Sherin's Law would also make it a felony for not reporting a missing child within a few hours.

It will be quite some time before the law could be introduced, but advocates told WFAA that several representatives have already expressed interest in helping.
