A case against a Lawrence man accused of stabbing a 15-year-old in a city park has been dismissed, after the victim wouldn’t cooperate and didn’t show up to court, Douglas County District Attorney Charles Branson said Thursday.

Branson said his office filed a new charge of felony aggravated battery against the suspect, Clayton Cumpton, 21, for allegedly hitting another 16-year-old victim.

Police arrested Cumpton on April 5 after a fight between two groups of people in Hobbs Park, near 11th and Delaware streets.

Cumpton was arraigned on the new charge June 23 and a jury trial has been scheduled for Sept. 9. He was released from jail June 11 on $5,000 bond.
