Katsina Lynnea Roybal was 21 when she was shot dead on the front porch of her East Denver home on the evening of July 12, 2010. She was a student at Metropolitan State College of Denver and helped raise her two younger sisters. On that warm night, she was sitting on the porch with a male companion when two unidentified men approached and opened fire. Katsina was struck in the head and pronounced dead at the scene; the man was shot in the leg, ran for help, and survived.

Investigators say the shooters may have used as many as three different firearms, and a witness and physical evidence were recovered, but the two suspects were never identified and no arrests have been made. The motive remains unknown and the case is still unsolved; a reward is being offered for information that could lead to an arrest and conviction.

Does anyone have information about that July 12, 2010 shooting or memories of Katsina that could help bring her family answers?
