A group of teenagers is accused in connection with the fatal assault of a “good Samaritan” grocer, and investigators are using evidence from the youths involved to determine what roles each played, according to reports.

The outlets say photo evidence of the teens’ injuries is part of the material being considered, alongside hand swabs taken from the teens. The combined evidence is intended to help investigators link alleged actions during the incident to specific individuals in the group.

Both reports describe the same focus on the forensic evidence, but they do not provide further details about the circumstances of the death, the exact number of teens involved, or the specific allegations against each teenager. The reports also do not state the current status of charges or the procedural stage of the case.
