The man accused of training children at his New Mexico compound to become school shooters is the father of a missing boy who is now feared dead after remains were found near the compound.

As CrimeOnline previously reported, the Associated Press obtained court records that show Siraj Ibn Wahhaj is accused of teaching children at the compound to use firearms, reportedly with the goal of committing school shootings.

Authorities discovered the compound while searching for Wahhaj’s missing son. The boy was not found at the compound during Friday’s raid, but 11 children were found living there, hungry and filthy.

Investigators subsequently found human remains near the property and are working to identify them. They also found firearms at the compound.

According to 11Alive.com, interviews with the children rescued from the compound indicate that the missing boy, Abdul-Ghani Wahhaj, died there and was buried in the area. The report does not specify how the boy is believed to have died.

Abdul-Ghani has been missing from his Atlanta-area home since December. According to an Associated Press report, his father said he was taking the boy to a park and didn’t return, sometime after telling the boy’s mother that he wanted to perform an exorcism on Abdul-Ghani.

The boy is reportedly unable to walk and requires round-the-clock medical care.

Wahhaj and four other adults living at the compound are facing child abuse charges, and Wahhaj has been issued an arrest warrant in Georgia on kidnapping charges.
