There are mounting legal problems for the Georgia-based firearms company that made the weapon used in the recent mass school shooting.

A Texas attorney is examining if Daniel Defense, a gun manufacturer, is liable for the Robb Elementary masscre due to its marketing campaign. Attorneys representing the father of a 10-year-old student killed in the mass shooting at an elementary school in Uvalde, Texas, that left 21 people dead filed a letter on Friday demanding answers from the Savannah-based gun manufacturer.

Daniel Defense made its Twitter account private shortly after the shooting, and deleted its most recent post, which depicted a young boy holding a Daniel Defense firearm with the caption, “Train up a child in the way he should go, and when he is old, he will not depart from it,” a reference to a Bible proverb, followed by a prayer emoji.
