In the statement, Cheseto thanked those who participated in a massive, almost city-wide search of trails and streets.
"As some may know, I've been going through a lot of personal issues," Cheseto said. "While I am still recovering -- both physically and emotionally -- I will do my very best to give back to the community that has helped me so much and to my home country, Kenya.
"I sincerely apologize for any problems that I might have caused."
