Katie Reid, 62, died on June 6, 2016, after being shot in the head at her Apopka, Florida, home. Her husband, Darrell Reid, 63, reportedly fired the gun while cleaning it; Katie was taken to Florida Hospital Apopka and later pronounced dead. The Orange County Sheriff’s Office opened a death investigation and at the time Darrell Reid had not been arrested or charged, with the shooting described as accidental and the investigation continuing.

The Reids were both pastors at Happy Hill Ministries and had been married since 1980, having known one another since age 12. Neighbors and a family friend described a troubled private life; deputies had responded to 23 calls for service at the couple’s home over the previous three years, and Darrell Reid had a criminal history that included a 2014 arrest for aggravated battery with a deadly weapon that was not prosecuted.

What details about the shooting or the couple’s history might help explain how this incident happened?
