FAIRBURY, Neb. (AP) — A grand jury has found no criminal conduct in the death of a 29-year-old inmate at the Jefferson County Jail.

The grand jury met Friday and concluded that no criminal conduct had contributed to the August death of Keylee Gibbons.

Authorities say Gibbons had been found unresponsive in her cell. Paramedics were called, and Gibbons was taken to a hospital where she later died. She’d been arrested on suspicion of possessing illegal drugs.

State law requires grand juries to investigate whenever someone dies in custody or while being arrested.
