However, poor record keeping and claims from different historians place his last known sightings from 1918 to 1929, making it unclear when his actual disappearance occurred. |
| September 1921 | Dick Rowland | 19 | Tulsa, Oklahoma, U.S. | Tulsa race massacre probably began because Rowland, an African American shoe shiner at a nearby store, tripped in an elevator and grabbed onto Page, a white elevator operator, to avoid falling, causing Page to scream, and a witness probably mistook this for an attempted rape. A small number of sources theorize that Rowland and Page could have been lovers who were having a lover's quarrel in the elevator. It is uncertain if either Dick Rowland or Sarah Page was their real name, and Sarah Page has been theorized to have been as young as 15 or as old as 21, although most sources agree she was 17. Rowland himself survived the Tulsa Race Riot, likely because his police protection in jail ironically made him safer than almost any other black person in Tulsa. Both Page and Rowland disappeared after Page helped get the charges against Rowland dropped following the Tulsa Race Riot, and nothing is known for sure about the rest of their lives. |

She never did, and the ensuing investigation attracted national media attention. The girl was never located, and the case remains the oldest unsolved missing-persons case of this nature in the files of the Chicago Missing Persons Bureau. A California woman's belief that she was Mary Agnes has subsequently been disproven by DNA testing. Familial DNA testing performed in 2023 determined that Jeanette Burchard, a Florida woman who had died in 2003, was indeed Mary Agnes Moroney. Though the results are conclusive, since Burchard's body itself has not been tested, and the perpetrator(s) have not been identified, the case is still officially unsolved. However, the Chicago Police cold case unit have pronounced the case closed. |
