Judsen Cunningham, on trial for causing a boating accident that killed two, is believed to have taken his own life early Thursday, the day his case likely would have gone to a jury.
Judge John Jay Gontarek convened court Thursday morning long enough to declare a mistrial and dismiss the jury.
Michele Nicholson, spokeswoman for the Okaloosa County Sheriff's Office, said deputies were called to Cunningham's family's home at 6:43 a.m.
