In this one-minute video series, Forensic Magazine is highlighting topics that have recently been in the media, either in the national headlines or fictionalized on procedural crime shows, and getting to the bottom of what these topics mean to the forensic community.

The trigger of a handgun seems like a really logical place to find a fingerprint, right? Actually, experts say that the chances of finding a latent print on a gun can be as low as five percent. That’s because guns are purposely designed with rough edges and surfaces around the trigger to provide extra grip, and often guns are wiped clean or disposed of after the crime making it really hard for investigators to find a good print. But researchers in Italy recently pulled fingerprints off of firearms using vaporized glue and wrote about their findings in the journal Forensic Science International.
