In the early morning hours of August 2, 2023, deputies answered a cardiac arrest call to the 600 block of Longwood Court in Edgewood and found 33-year-old Tyrell Orlando Polley inside a residence. Polley had suffered multiple gunshot wounds to his upper body. Reports note he had survived a prior shooting years earlier that left him with impaired vision.

Harford County Sheriff’s Office detectives and crime scene investigators led the response, conducting an extensive search for witnesses and physical evidence and using technology to identify a person of interest. On August 15, 2023, an arrest warrant was issued for Michael Anthony Brown, Jr., 37, of Brooklyn, Maryland; Brown was already in custody in Baltimore County on unrelated charges when the new warrant named him in connection with Polley’s death, alleging first- and second-degree murder and first- and second-degree assault. The investigation is ongoing.

If anyone knew Tyrell, witnessed events on Longwood Court that night, or has information that could help investigators, please come forward.
