The streaming platform dropped the clip on social media on Thursday (8th October) ahead of its premiere on October 19th.
Much like Volume 1, the second instalment will contain six episodes, and will delve into old mysteries which have never been solved, looking for clues and appealing for new evidence.
Check out the trailer below:
Speaking to Variety after the first volume aired, executive producer Terry Dunn Meurer said that we can expect two more international cases as well as an "unusual" ghost story in the second instalment.
And he certainly came through. As far as what we can expect from Volume 2, the episodes focus on a variety of cases including stolen kids, the Washington Insider Murder, tsunami ghosts, a lady in a lake, a death in Oslo and a death row fugitive.
Addressing one case in the upcoming series, the new trailer says: "Why is it important to find out why a person died 25 years ago? People die all the time...
"I think it's important for the family to know what happened to her."
The true crime series is a reboot of the NBC and CBS show that ran for 12 years between 1987 and 1999.
We've previously seen cases like the unexplained death of Rey Rivera (could he really have fallen through that hole in the roof of the Belvedere Hotel in Batimore?) and the mysterious disappearance and murder of hairdresser Patrice Endres in Cummings, Georgia.
There's also the tragic case of Count Xavier Dupond de Ligonnes' wife and four children - who were found dead under the porch of their family home back in 2011.
A manhunt ensued after he was believed to have murdered them, but he was never found.
The fourth episode in the series focuses on the case of Alonzo Brooks, who had been missing for one month when police found his body in an area they had already searched.
While detectives are still trying to piece together the night Alonzo went missing, witness reports suggest, as a man of Mexican and African-American parentage, he was at a party where he was one of the few people who wasn't white, and was the subject to racial slurs throughout the evening.
Following the release of the first six episodes, show creators saw a surge in tip-offs from viewers.
Meurer claims that the team received over 1500 tips, with around 50 flagged as possible leads and passed on to law enforcement agencies.
If you haven't watched Unsolved Mysteries yet, we suggest you catch up ASAP before Volume 2 arrives.
