Thomas Sebastinelli, 48, a male from Dallas, was found shot in the early hours of Sunday, September 21, 2025, on the 4100 block of Cedar Springs Road in the Oak Lawn neighborhood. Officers responded at about 1:20 a.m., and Dallas Fire-Rescue pronounced him dead at the scene. The street—home to late-night foot traffic and weekend parade routes—was cordoned off as detectives set about reconstructing the moments that led to the gunfire, a sudden rupture in a corridor that is usually loud with music and conversation.
By late morning, police named a suspect and moved swiftly to make an arrest. Investigators identified 32-year-old Earnest Polk as the man they believe shot Thomas Sebastinelli, 48, male, and took him into custody on a charge of murder. Jail records reflected that Polk was booked at 8:41 a.m., hours after the shooting, as detectives secured the scene and notified next of kin. The department opened case number 136097-2025 and asked anyone who saw or heard anything to contact Detective Ronald Kramer as they reviewed evidence and canvassed for additional witnesses.
In the days that followed, the outline of the case remained stark: a fatal encounter before dawn, a victim—Thomas Sebastinelli, 48, male—whose life ended on the pavement, and a suspect in custody as prosecutors prepared to evaluate the evidence for formal proceedings. Community posts and memorial pages recorded his name and age, while local outlets tracked the investigation’s steady, procedural steps rather than any dramatic twists, signaling that the central facts were settled even as the motive remained a matter for detectives and, eventually, the courts.
