Officers caught up with the victim’s husband, 56-year-old Hilario R. Hernandez, in Kingsville later in the day and arrested him.

A spokesperson for the Houston Police Department confirmed the suspect was employed with agency. Police in Pearland said they were conducting “business as usual” while investigating the homicide.

“The law is held accountable for everybody,” said agency spokesman Jason Wells, adding that the adage is especially true when applied to fellow law-enforcement officers.

Police have not confirmed that anyone heard the fatal gunshots and had the neighborhood cordoned off much of the day Saturday as they conducted the initial investigation.

Hilario and Belinda Hernandez had reportedly been married for more than 30 years and had two adult children.
