Unknown Serial Killers of America, the newest addition to Oxygen‘s true crime lineup, exposes a collection of killers as deadly as society’s most infamous, who are little known to the general public. Through conversations with law enforcement and those closest to the victims, the six-parter explores how these murderers were able to remain under the radar, continuing to kill for as long as they did.

Rolling out in weekly hour-long episodes, the series premieres on Sunday, May 18, with Carl Watts as its subject. A murderer with 100+ victims, Watts marks the first-ever serial killer set to be released from prison. Airing at 7 p.m. PT/ET on Oxygen, cord-cutters can watch on any live TV streaming service that carries the channel, including Fubo, DirecTV and Hulu + Live TV.

Since select streamers are offering free trials, new subscribers can watch the premiere at no cost. Keep reading for each option.
