A man in California accused of killing his wife allegedly told police that he bludgeoned her to death with a concrete block after powerful people infected him with mayonnaise.

Nathaniel Robertson, 46, was arrested on July 12 for murdering his wife, Lidia Robertson, 57, who was reportedly found dead at their home on July 11 with head trauma, surrounded by a pool of blood next to a large concrete block. KGET reported that a neighbor told police that she heard arguing from their home the night prior before spotting Nathaniel Robertson leave the residence and return with a large rock.

Neighbors went on to tell KERO-TV that they heard screams coming from the Oildale home on the night Lidia Robertson died.

Nathaniel Robertson told Kern County deputies that he struck his wife with the cement brick at least four times “to give her compassion and mercy,” sparing her from a powerful group who would “do brutal things to people, like eat them,” a police report obtained by The Bakersfield Californian stated.

While police claimed Nathaniel Robertson admitted to using crystal methamphetamine of the day he killed his wife, he allegedly also said the unidentified group injected mayonnaise into his leg, which became infected. He said whatever they injected into him with releasing information to him from the Revolutionary War, according to the news outlet.

“I didn’t want it to be a painful thing,” he reportedly told investigators. “I didn’t want to hit her a bunch of times, I wanted to end it, I didn’t want her suffering.”

KGET reported that officers apprehended Nathaniel Robertson at a nearby park. He reportedly claimed he went there because he was looking for a place to take his life.

Nathaniel Robertson pleaded not guilty to first-degree murder charges. A pre-preliminary hearing is scheduled for July 31.
