The father of a 16-year-old Lincoln boy who hanged himself in a youth detention center has filed a lawsuit accusing county officials and employees of deliberate indifference to the teen’s mental illness and suicidal statements.

The Lincoln Journal Star reports that the lawsuit filed in Lincoln’s U.S. District County names Lancaster County and five unnamed employees as defendants.

Detention center staff found Jonathan Kennedy unresponsive in his cell the night of Feb. 26. He was taken to a local hospital, where he later died. The teen was being detained due to suspected drug use and self-harming behavior.

In the lawsuit, the teen’s father says detention center staff should have protected the teen from himself. The lawsuit seeks funeral expenses and an unspecified amount for other damages.
