What initially was called a suspicious death has become The City’s 53rd homicide of the year, a police spokesman said.

The death of a 67-year-old man was reported Sunday at 2:05 p.m. inside a residence on the 700 block of Polk Street, and was initially reported as a suspicious death, police spokesman Sgt. Wilfred Williams said Thursday.

“Upon further examination by the medical examiner, it was determined that the victim had blunt head trauma injuries consistent with a murder,” according to Williams.

Police have not taken anyone into custody in connection with the homicide, but “are investigating possible leads,” Williams said.

At the same time in 2007, when The City recorded a decade-high 98 homicides, there were 54 homicides.
