Friends and family of Madison Robinson, a 15-year-old who was shot and killed in August, demonstrated in front of the Cape Girardeau city courthouse and police station Saturday, Dec. 7, 2019, to call on the Cape Girardeau County Prosecuting Attorney's office to bring charges against a suspect in the case. In the hours after the shooting, police arrested Isaiah M. Lane, 29, and charged him with one count of first-degree murder, two counts of armed criminal action, unlawful use of a weapon by shooting at a home and possession of a firearm by a felon. Last month, Cape Girardeau County assistant prosecutor Angel Woodruff dropped the charges due to "a lack of witness cooperation," according to previous reporting by the Southeast Missourian. Police said Saturday the case was still under investigation and progress is being made.
