A Douglas County prosecutor told a judge Tuesday morning the state had a “very strong case,” including a confession, against at least one defendant in a recent robbery of two men at a south Lawrence apartment.

Kathleen Britton, an assistant Douglas County district attorney, made the comments when she asked District Judge Peggy Kittel not to lower bond for defendant Joshua S. Self, 18, in the aggravated robbery and aggravated battery case.

Kittel denied a request from Self’s attorney, Napoleon Crews, to lower his client’s bond from $100,000 to $5,000.

Self, his brother, Christopher D. Self, 19, and Douglas A. Bittinger, 19, all of Lawrence, each face two aggravated robbery charges, two aggravated battery charges and one count of conspiracy to commit robbery.

Prosecutors accuse the men of using a gun to rob two 20-year-old Lawrence men the evening of Sept. 6 at an apartment at The Exchange, 3100 Ousdahl Road. Prosecutors allege Joshua Self and Bittinger battered the two men and that one victim was knocked unconscious and needed staples in his head to repair a wound. Christopher Self is accused of driving his co-defendants to and from the apartment.

All three defendants are scheduled to appear in court again next Tuesday.
