HOUSTON, TX — A Houston man is facing a murder charge after police say he stalked, tracked, and ultimately stabbed a woman to death inside a restaurant where she worked.

According to the Houston Police Department, Santos Hernandez Cornejo, 53, was arrested and charged in connection with the fatal stabbing of 50-year-old Argelia Diaz Maya early Saturday morning.

The attack occurred just after midnight on June 14 at the Burnin’ Shell restaurant on Wilcrest Drive, in Houston, Texas.

Officers arrived at the scene around 12:10 a.m. to find Maya suffering from multiple stab wounds inside the business, according to police.

She was pronounced dead at the scene by responding paramedics from the Houston Fire Department.

Investigators with HPD’s Homicide Division said Hernandez Cornejo, who had been in a relationship with Maya, confronted her in the restaurant’s parking lot following an argument. She tried to escape by running into the building, but police say he chased her inside and stabbed her multiple times before fleeing on foot.

Court documents obtained by KTRK-TV allege Hernandez Cornejo had been obsessively monitoring Maya in the days leading up to the attack. He reportedly admitted to investigators that he believed she was cheating on him and had installed both a tracking device on her vehicle and a listening device in her bedroom.

Describing the killing as both “very aggressive” and “calculated,” court officials said Hernandez Cornejo later called police to turn himself in. According to court records cited by KTRK, the murder weapon—a bloody knife—was recovered in a nearby field.

During his initial court appearance, Hernandez Cornejo’s public defender emphasized his cooperation with police and voluntary surrender. However, the prosecutor requested a $300,000 bond, arguing the premeditated nature of the crime warranted higher bail. A judge ultimately set bond at $350,000.

Hernandez Cornejo, a Salvadoran national who told the court he has lived in Houston for 17 years, is currently being held at the Harris County Jail under an immigration detainer, according to court records.

A coworker told KTRK the victim worked as a dishwasher at the restaurant where she was killed.

The case remains under investigation.
