Law enforcement officials in Louisiana say a man has been arrested after he allegedly placed a tracking device on his estranged wife’s car, randomly showed up at her work unannounced and later killed her.
On March 20, deputies responded to a home in Ponchatoula, where they found 45-year-old Lisa Hernandez covered in blood on the ground between her bed and a dresser, according to the Tangipahoa Parish Sheriff’s Office.
First responders performed lifesaving measures on the victim, but they were unsuccessful.
Investigators identified the victim’s estranged husband, 49-year-old David Hernandez, as the primary suspect in the case.
Authorities said the couple separated and a year after that separation, David allegedly started “stalking Lisa and would randomly show up at her place of employment.”
He also reportedly sent her a bouquet of flowers that included lilies, which she is “highly allergic” to and they are also known as the “death flower.”

Investigators also found a tracking device on Lisa’s vehicle, which had “been linked to David.”
On the day of Lisa’s death, police said David “staged a burglary,” then dumped evidence into Lake Pontchartrain. Investigators were able to eventually recover the specific items he dropped in the water.
On April 15, Hernandez was arrested and charged with second-degree murder and obstruction of justice, officials said. He was booked into the Tangipahoa Parish Jail.
