An American woman has been charged with the murder of her husband after detectives discovered a chilling Google search she made just days before her partner’s death.

Sandra Louise Garner, 55, from Maypearl, Texas, was arrested on January 10, nine days after husband John Garner was murdered at their home on January 2.

After seizing an electronic device from the address, detectives found a Google search “how to kill someone and not get caught” just days before the death, Waxahachie Daily Light reported.

Police Chief Boyd Norton said the autopsy revealed that John Garner was killed via a bullet wound.

His wife told investigators that an intruder had entered their home, revealed to her that he had a work-related disagreement with her husband and shot him dead.

She also said the man forced her to open the family safe before making off with $18,000.

But on January 4, the Maypearl Police Department wrote on Facebook: “We have reason to believe that the shooting was NOT a ‘stranger on stranger’ home invasion.”

After discovering a bullet inside a pillowcase during a search at the couple’s home, detectives seized Garner’s electronic devices before discovering her internet history.

Police also found a gun in a Ford Mustang parked near the address which experts confirmed matched with the bullet found inside the body.

Garner was arrested and charged with the murder of her husband.

She remains in the Ellis County Jail with bail set at $2m.
