In an interview late Thursday, Mr. Green, who runs a sportswear company in Florida, confirmed that the picture was genuine, and that the F.B.I. had contacted him and requested a copy. “I have spoken to several agents,” Mr. Green said, “and they have got the photos, they are picking up material from me, and I don’t think there’s any doubt.” Mr. Green said he took the photo at 2:50:15 p.m. on Monday.
