On the night of January 9, 2022, 24-year-old Trishay Marsean Thompson drove with two friends to an apartment complex in the 1400 block of Pennsylvania Avenue in Des Moines for a drug transaction arranged over Facebook Messenger. The deal was cancelled after further messages, but shortly afterward two men came out of the apartment building and opened fire on the vehicle where Thompson and his friends were seated.

Thompson was critically wounded and taken to a local hospital. He remained hospitalized for weeks and died of his injuries on the morning of January 27, 2022; his death was the city’s first homicide of the year. Police described the shooting as an attempted robbery during a drug deal and opened an intensive investigation into the case.

Did anyone who lived near the 1400 block of Pennsylvania Avenue that night or who used Facebook Marketplace see or hear anything that could help investigators?
