Eric Duff, 32, was shot and killed inside his North Fort Myers home on Guest Court on February 8, 2017. Deputies from the Lee County Sheriff’s Office responded at about 2 a.m. and found Duff dead inside the residence. Investigators reported no signs of forced entry, and evidence suggested the attacker was likely someone Duff knew.

Duff was described as a talented athlete and a devoted father; he left behind an eight-year-old daughter and close family who have spoken publicly about his loss. A year after the killing two people, Martell Eugene Gray and Kaitlyn Belle Gillespie, were arrested on evidence-tampering charges tied to the scene and later received terms of supervision and probation; Gillespie’s probation was revoked for violations and she was serving a prison term. The primary suspect in Duff’s murder has not been identified and the case remains open.

If anyone knew Eric, was in the Guest Court neighborhood that night, or has information that could help identify who killed him, please share what you know with investigators.
