A Texas woman is in jail on suspicion of her husband’s murder after investigators found an incriminating entry in her web search history.

According to the Waxahachie Daily Light, police say 55-year-old Sandra Louise Garner looked up “how to kill someone and not get caught” on an internet-connected device shortly before her husband, 42-year-old Jon Garner, was found dead in the couple’s home on Jan. 2.

She was arrested Wednesday in connection with the shooting death. The Fort Worth Star-Telegram reports she was jailed with bond set at $2 million.

When Sandra Garner initially contacted police dispatchers to report the shooting, authorities say she claimed that she “was awakened by two gunshots and saw a masked male holding a gun and flashlight inside of her residence.”

Reports indicate she went on to describe a robbery by the man she said “held a grudge against her husband because of work-related matters.”

The suspect initially accused the intruder of demanding $18,000 from a safe inside the residence.

During a second search of the home several days after the shooting, investigators reportedly found a handgun inside a car parked outside, which matched the caliber used to kill Jon Garner.

“Investigators noted this vehicle was searched during the first search at the residence on Jan. 2 and did not find this firearm,” according to Maypearl Police Chief Boyd Norton. “It was apparent this firearm was moved to the vehicle after the initial search conducted on Jan. 2.”

A subsequent comparison of the .38-caliber Taurus handgun found in the vehicle and evidence left at the scene indicated a match, according to analysts.
