Authorities in Texas arrested a man who they say killed his fiance after he asked Google, “Can I kill an illegal human,” because the victim was reportedly an undocumented immigrant.

Ty Vaughn, 31, is charged with murder in the January death of 27-year-old Luis Banos Norberto. Vaughn is accused of shooting Norberto in the face and then moving his body in an attempt to make it like a suicide, a criminal complaint says. It happened Jan. 14 at an apartment complex in Baytown, which is near Houston.

Local ABC affiliate KTRK obtained an arrest affidavit that further details the allegations against Vaughn. He claimed he came home shortly after 5:30 a.m. to find Norberto dead, but surveillance video and interviews with neighbors told a different story. Video showed that Vaughn actually returned home shortly after 4 a.m., the affidavit reportedly said. Neighbors reported hearing a gunshot a few minutes later.

Around 4:30 a.m. as Norberto lay dead in the apartment, Vaughn allegedly texted the victim, “Babe? Babe why are you not texting back?!?!” Cops reportedly said Vaughn waited until after 5:30 a.m. — some 90 minutes after the murder — to call 911.

“My spouse is dead,” he allegedly told dispatchers. “Help. My life is over.”
