On September 9, 2023, brothers Alexis Martinez Marquez, 19, and Osvaldo Martinez Marquez, 16, were found shot to death in an abandoned section of a duplex at 10214 SW 175th Street in Southwest Miami‑Dade. Emergency calls came in around 5:22 p.m.; Miami‑Dade Fire Rescue confirmed both were deceased at the scene and the Homicide Bureau is leading the investigation.

Neighbors and family members, including parents Sita and Jose Martinez, held a vigil and temporarily blocked a street to mourn the brothers and call for justice. Authorities have not released details about suspects, motives, or leads. Miami‑Dade Crime Stoppers is offering up to a $10,000 reward for information leading to an arrest. It is unclear how anyone gained entry to the abandoned portion of the house where the killings occurred.

If anyone has information that could help identify those responsible, contact Miami‑Dade Crime Stoppers.
