On April 4, 1990, six people were killed in a mass shooting at a house on St. Aubin Street in Detroit. Victims were 15-year-old Robert Lee Hill, 16-year-old Bobby Lee Frazier, 21-year-old Carl D. Williams, 18-year-old LeVon Robinson, 22-year-old Rodney Lamarr Lewis, and 32-year-old Steven Owens. The killings followed a planned robbery targeting a reputed crack house run by Owens.

Prosecutors said the robbery was organized by 18-year-old Tamara Marie Marshall, with 19-year-old Jamal Latif Biggs, 20-year-old Mark Bell, and Marc Caison taking part. Five victims were reportedly shot inside the house; LeVon Robinson arrived afterward, was taken to the basement and then shot. The perpetrators left with under $2,000, some cocaine, and personal items.

At trial, Marshall was convicted of three counts of first-degree murder, two counts of second-degree murder and as an accessory in one killing. Biggs was convicted of first-degree felony murder in Robinson’s death and second-degree murder for the others; Bell was convicted of first-degree murder. All three received mandatory life terms without parole. The fourth defendant, Marc Caison, was to be tried separately. Anyone with information about Robert Lee Hill or the events of April 4, 1990, is asked to come forward.
