Police have arrested a 21-year-old man in Texas for plotting to murder, rape and eat a young girl.

According to a “probable cause affidavit,” Alexander Nathan Barter was arrested after allegedly communicating with an undercover officer.

Barter posted on the web asking for anyone interested in allowing him to commit necrophilia and cannibalism to reach out to him.

An undercover special agent with the Texas Department of Public Safety saw the post and responded. The agent offered up his “young daughter.”

The affidavit said Barter replied, “Nice! I’m in East Texas. How old is your daughter? Can we kill her?”

Through several exchanged emails, Barter allegedly created a plan to meet up with the “father and daughter.” The agent claimed Barter said he would take the girl to a hotel to kill, assault and eat her.

“I’m not going to change my mind about this,” Barter wrote. “I really want to do this,” he said, per the affidavit.

Barter was arrested outside of his residence when he went to meet the undercover agent and the daughter. He had a plastic trash bag and knife with him, the affidavit said. He also admitted to being in contact with the undercover official and making the statements attributed to him in the affidavit.

Barter was charged with criminal solicitation, criminal attempt capital murder, conspiracy to commit capital murder and criminal attempt sexual performance of a child.

District Attorney Stephen Shires shared a statement saying, “The web, and the individuals that operate there, pose an increasing threat to the safety of our children. Technology has eliminated the barrier of distance for these sort of activities.”
