HOUSTON, Texas (KTRK) — It’s been just a little more than two weeks since investigators believe Johna Robinson shot and killed 52-year-old Terribia Dembry.

Since then, there have been several developments in the case. On Friday, Robinson was arrested by federal authorities in a northwest Houston neighborhood.

The reason why Robinson, who is a convicted felon, was a wanted man is because court records show he posted bond on a charge of “unlawful possession of a firearm” before he was charged for Dembry’s murder.

But there is disagreement over whether the murder charge was filed before or after he left jail.

Now, investigators say someone could have been helping Robinson while he was out.

According to court documents, Samone Emerson has been charged with tampering with or fabricating physical evidence and hindering apprehension.

Investigators say she tried to destroy or hide clothing connected to the murder.

Court records also say investigators believe Emerson helped Robinson avoid arrest by providing aid or helping him escape, knowing he was a wanted man.

As the investigation continues, authorities have not said how Emerson and Robinson know each other.
