On January 23, 2023, Alexandra Olmo, 43, and her 21-year-old transgender daughter, Jael Omar Burgos, were fatally shot during a mass shooting at a second-floor unit in a courtyard building at 2909-19 E. 78th St., near Exchange Avenue in Chicago’s South Shore neighborhood. Police say two teens wearing ski masks, one in camouflage, kicked in the apartment door, demanded money and opened fire. Three others were critically wounded; one wounded survivor ran over half a mile to a McDonald’s at 79th Street and Phillips Avenue to get help. The restaurant was later cordoned off.

Authorities have described the incident as a targeted home invasion and said the investigation is ongoing. A $15,000 reward was offered for information leading to the shooter(s). A 19-year-old was identified in photo lineups and arrested on January 26, 2023, but prosecutors declined to charge him and he was released on January 29. The family has expressed frustration and confusion about the handling of the case and limited information about the investigation.

Did anyone in the South Shore area see or hear anything that night that could help investigators?
