On the night of October 1, 2017, a downtown Lawrence street fight near 11th and Massachusetts Streets ended in a barrage of gunfire that left three people dead, including 20-year-old Colwin Lynn Henderson of Topeka. Police heard at least 20 shots; two other people suffered non-life-threatening injuries. Henderson had attended an event at the Granada theater earlier that evening and was described by family as a new father to a 10-month-old daughter who was trying to turn his life around.

Investigators say the shooting followed an earlier physical altercation. Testimony at a later trial reported that Anthony L. Roberts Jr. traveled from Topeka to Lawrence with companions to confront a rival group, an argument turned into a fight, and Roberts began firing a handgun with an extended magazine, firing at least 15 rounds into the crowd. Evidence presented at trial indicated Henderson was bent over, punching another man when he was shot in the back.

Roberts was convicted by a Douglas County jury on counts that included second-degree intentional murder for Henderson’s death; others who were with Roberts that night were also charged. Did anyone who was in downtown Lawrence that night or who knew Colwin see activity around 11th and Massachusetts before or after the shooting?
