What to Watch Saturday: 48 Hours has Israel Keyes update, SNL’s at-home season finale

48 Hours (10 p.m., CBS) - Peter Van Sant gets the first look at new evidence in the FBI’s search to identify the victims of notorious serial killer Israel Keyes. Keyes was first arrested in 2012 in connection with the disappearance of a young woman kidnapped from a coffee stand in Alaska. Since then, Keyes has been exposed as one of the most diabolical serial killers in American history. Some of the cases linked to Keyes have been revealed through drawings Keyes made with his own blood, which Van Sant shows in his report, along with “kill caches” containing guns, zip ties and other items obtained by the FBI and believed to have belonged to Keyes.

Saturday Night Live (11:30 p.m., NBC) - SNL will close out its 45th season with another at-home episode. Paul Rudd will host the finale.
