Conner said authorities believe the victim will survive but he remains in critical condition with life-threatening injuries, including significant wounds to his face.

Due to the extent of the man’s injuries, detectives have not been able to learn anything from the victim about the circumstances or the identity of his attacker. Police don’t know whether he was randomly targeted or whether his assailant was someone he knew, Conner said.

Conner said there is no surveillance video that “actually captured the incident.”

However, Conner said a detective on Thursday canvassed the building where the assault occurred, as well as adjacent buildings, “to locate surveillance video to try and see what we can find.”

Conner said at this point, it doesn’t appear the man was robbed. “But because we still haven’t been able to do a full interview with him, we’re unable to determine if, in fact, anything is missing from his person or his office.”

Conner said detectives are looking at whether the victim had any negative interactions with customers or other people that may have led to the attack.

“We’re really still in the preliminary stages” of the investigation, Conner said.
