Denver prosecutors will drop all charges against a Black man accused of killing two white brothers in a road-rage incident on Interstate 25 last year. Stephan Long, 26, was initially charged with two counts of first-degree murder in the June 13, 2023, killings, but said he acted in self-defense when he shot the two men after they rushed his car in stopped traffic. Prosecutors dropped one of the first-degree murder charges against Long in October, saying they could not prove the charge in court — but the murder case continued for the second brother. Prosecutors on Wednesday informed the brothers’ family members that they plan to drop the second murder charge as well, said their father, Arthur Lucas. “This system has failed me,” he said.
