After I had my home broken into the guy taking fingerprints explained to me that fingerprints don't really work like that. You're lucky to pull one single print out of an entire house, regardless of how careful a burglar was. So I suspect that finding one good print and extrapolating a suspect from it is probably pretty common. Flawed obviously, but common.
