Sandra Garner, from Maypearl, Ellis County, Texas, has been charged with the murder of her husband Jon Garner on 2 January.
The find of the firearm was incriminating because the gun did not seem to be in the auto during an earlier search by police after the shooting of Garner's husband was first reported.
A Maypearl, Texas, woman is facing some serious legal trouble after she was arrested Wednesday night on suspicion of murdering her husband, and the details of the case are as dumb as it gets.
Sandra Louise Garner was picked up on Jan 10, only nine days after her husband's murder.
He also threatened to come back and kill her if he heard police sirens at the home, Garner told investigators.
Norton said Garner called 911 that night, claiming she "was awakened by two gunshots and saw a masked male holding a gun and flashlight inside of her residence".
"Ms. Garner said she was instructed to open their home safe and gave the intruder approximately $18,000".
Police later analyzed electronic devices in the home and discovered Sandra Garner's telling online search.
"Investigators noted this vehicle was searched during the first search at the residence on January 2 and did not find this firearm", according to Maypearl Police Chief Boyd Norton. Police said the gun, which matched the one that was used to kill Jon Garner, had been wrapped in a paper towel and hidden inside two plastic bags.
"It was apparent this firearm was moved to the vehicle after the initial search", Norton told the Waxahachie Daily Light. Maypearl Police Chief Boyd Norton said that the autopsy revealed that John Garner was killed with a.38 caliber bullet. Police arrested Garner and charged her with Murder.
A funeral for Jon Garner, who worked as a general manager for DHL Express and We Pack, will be held on Saturday in Waxahachie.
