No suspect(s) in Al Tariq Brown Shooting

I can't find any updates on the Al Tariq Brown murder that took place in March.  Has anyone heard if any suspects were identified?

Does anyone know whether they ever caught anyone in this case?

The last thing I can find is a reference in this article from March.

Apparently his cousin was murdered in March at an event honoring Al-tariq's memory. This article mentions the investigation and that no suspects had been identified.
