Daniela Marie Blackburn, 38, died on July 14, 2022, in Marathon, Florida. Her boyfriend, Sean Booth Chidester, called 911 and said Blackburn had shot herself in the head while he was in another room. First responders found Blackburn with a gunshot wound to the head and a 9mm handgun nearby.

The Monroe County Sheriff’s Office and the medical examiner found inconsistencies with Chidester’s account. The medical examiner concluded the wound was not consistent with a self-inflicted gunshot. Detectives also documented a history of domestic violence; Blackburn had called 911 earlier in June to report multiple assaults by Chidester but had declined to press charges then. A no-contact order issued June 18, 2022, was later found to have been violated.

As the investigation progressed, the State Attorney’s Office charged Chidester with dangerous and depraved murder without premeditation, kidnapping, and two counts of violating the no-contact order. He was held in jail on $1 million bond. Does anyone with knowledge of Blackburn’s life or the events in Marathon have information that could help the investigation?
