A Texas grandmother is praised after she heard her own grandson making threats to shoot people at a local hotel in Lubbock, Texas.

She immediately sent him to a hospital so he could get treatment and prevent him from going forth with his actions.

The boy was identified as 19 year old, William Patrick Williams.

Less than a month before two deadly shootings claimed the lives of 31 people in El Paso, Texas, and Dayton, Ohio, a Texas grandmother stopped another mass shooting before it began.

William Patrick Williams, a 19-year-old from Lubbock, Texas, told his grandmother that he had purchased an AK-47 rifle and planned to “shoot up” a local hotel and “commit suicide by cop,” according to the U.S. Attorney’s Office of the Northern District of Texas.

Concerned for his safety and for the safety of others, she convinced her grandson to let her take him to a local hospital, a news release said.

During the investigation, federal agents discovered Williams had “misrepresented” his current address on the firearms transaction form when he purchased the rifle. After a brief hospital stay, he was arrested Thursday on suspicion of making false statements to a firearms dealer.

“This was a tragedy averted,” U.S. Attorney Nealy Cox said in the release. “I want to praise the defendant’s grandmother, who saved lives by interrupting this plot, as well as the Lubbock police officers and federal agents who investigated his unlawful acquisition of a deadly weapon.”

Officers searched the room Williams rented at the hotel he planned to target and found the rifle, 17 loaded magazines and multiple knives. Williams told authorities he laid out his weapons so that they could take them.

We are so thankful that the grandmother sought help for her grandson after hearing his threats. She definitely prevented him from taking away innocent people lives. Everyone please pay attention to signs and warnings. If you hear or see something, say something.

And now you’re officially in the KNOW!
