The unit responds to child abuse over a wide area of central Florida.

GAINESVILLE — Four days after he fatally shot himself outside the White House, a Florida man’s apartment sat untouched by investigators on Tuesday. His roommates had not been questioned by police and didn’t even know that he had died.

An open, empty handgun case sat on the unmade bed of Cameron Ross Burgess in the Gainesville apartment he shared with two others on a tree-lined street just a few blocks from the University of Florida campus, where he worked helping abused children. There were nine rounds still inside the gun case.

Justin Ford was distraught when told of his roommate’s death by an Associated Press reporter, saying he had been texting Burgess for days about rent with no answer. He said he also hadn’t heard of the shots fired outside the White House.

“I must have seen him four days ago or something,” Ford said, adding that it wasn’t unusual for Burgess to leave for a few days at a time. “Sometimes he would just leave and go on a camping trip or something.”

Ford accompanied a reporter inside Burgess’ room, and was shocked when he saw the gun case. Ford said the quiet, 6-foot-2, bearded man had been a gentle, generous roommate since he had moved in last August.

“I had no idea about him having a gun,” he said.
