Kyle Zepeda III was 45 when he was fatally shot while trying to help a family member on the afternoon of December 19, 2019. He and his wife went to a home on Camberly Street in Port St. John, Florida, because her brother, Daniel Diemer, was causing a disturbance in the garage apartment of his mother’s house. Zepeda approached the apartment’s side door unarmed; his wife’s cellphone recorded what followed. Diemer met him at the door, retrieved a handgun from a table inside, pointed it at Zepeda’s head and pulled the trigger. Zepeda was taken to a nearby hospital and later died of his injuries.

A neighbor who heard the commotion held Diemer at gunpoint until Brevard County deputies arrived. Diemer was arrested and charged with second-degree murder; investigators reported the mother wanted him to move out and that Diemer had said he shot Zepeda because he didn’t like him. After a court-ordered evaluation, a judge found Diemer competent to stand trial. A six-day trial concluded in February 2026 with a jury finding Daniel K. Diemer, then 32, guilty of second-degree murder.
