A former defense data analyst is held without bond in Florida after police say he stabbed his girlfriend to death.

We trust people with our nation's deepest secrets. But a quiet home in Florida became a crime scene after a man trusted with those secrets made a chilling phone call.

WHAT HAPPENED

On Friday afternoon, police say Kyle Sanchez, 35, called 911 from his home in Tampa, Florida. He told the dispatcher that he had killed his girlfriend, 37-year-old Amanda Roark. He said she was beyond help because he had a very unfriendly urge and grabbed a knife.

Just 10 minutes earlier, Amanda Roark had called 911 herself. Dispatchers could hear her begging for her life, but they could not get her address before the call ended. When officers arrived, they found Sanchez covered in blood and Roark dead from multiple stab wounds.

Sanchez worked as a data analyst at MacDill Air Force Base until May. He held a top-secret security clearance. He now faces a charge of first-degree murder.

WHAT THE EVIDENCE SHOWS

A 911 call from Amanda Roark at roughly 2:50 p.m. where she begged for her life.

• A confession call from Kyle Sanchez 10 minutes later at roughly 3:00 p.m.
• Police found Amanda Roark dead with multiple stab wounds to her upper body and neck.
• Kyle Sanchez was found covered in blood inside the three-story home.
• Blood was found on walls, doors, and furniture in multiple rooms.

THE BIGGER QUESTION

How does someone with a top-secret clearance slip through the cracks? The military screens these workers to make sure they are stable and safe. Yet, just weeks after leaving his job, a tragic act of violence occurred.

We must ask if our defense agencies are doing enough to support and monitor workers when they leave highly stressful roles. Are we missing the warning signs before it is too late?

THE OTHER SIDE

Sanchez does not have a listed attorney yet. He has not entered a formal plea, and he is receiving treatment for minor injuries.

Based on the recorded 911 calls from both the victim and the suspect, the defense will face a very difficult task in court.

WHAT HAPPENS NOW

Sanchez is held without bond until his court hearing on June 23. This tragedy leaves a family grieving and shows how fast domestic disputes can turn deadly.

Neighbors in the quiet Tampa area are left trying to make sense of the sudden violence next door.

WHAT WE STILL DON'T KNOW

1. What caused Sanchez to leave his job at the Air Force base in May?
2. Did the military notice any warning signs before he left his role?
3. What was the motive behind the sudden attack?
