Crash site photo album

Circa late 1970s, a neighbor and I began talking about UFOs.  He mentioned that his father-in-law was one of the officers who cordoned off the area around a UFO crash site (Roswell?).  His wife told him that her father had shown her a photo album of the crash site, including alien bodies, and that they looked “very real.”  He didn’t mention what became of the album.  I knew this person only briefly and don’t know his current whereabouts, but I remember his name and where he lived.
