Police say John Gavilanes was found dead in his car on Route 7. An investigation revealed the Gavilanes had a gunshot wound in his head and bullet holes on his Nissan Rogue. Gavilanes had been romantically involved with Mejia.

Investigations led police to a Nissan dealership, where they found the car allegedly used in the crime. Police were able to trace a Nissan Pathfinder to a male suspect.
