The Houston Police Department is investigating the death of a man found Wednesday morning outside Houston City Hall, apparently having fallen 10 to 15 feet into the crevice between the building and its back patio.

It was not immediately clear how long the man had been there before being discovered by contractors, who called HPD around 10:20 a.m., spokesman John Cannon said.

"It's unclear ... if he was up on this ledge to begin with in some way shape or form and just fell, either front or backwards," Cannon said.

The man, who was fairly well-dressed, did not appear to be homeless or wearing a City Hall badge, Cannon said.

Cannon said investigators were looking into whether cameras recorded any activity related to the man's death.

"Once we talk to some of the employees and contractors about how often that they go down there, when's the last time that somebody went down there and didn't see anything? All those will be part of the questions," Cannon said.

Houston Mayor Sylvester Turner's spokeswoman, Janice Evans, said she was not aware of anyone having previously ended up in the crevice bordering City Hall.

Asked if the city was considering any additional security measures in light of the incident, Evans said, "I don't think we're at that point, again not knowing what the circumstances were."
